A bag contains 3 red marbles, 8 blue marbles, and 2 Green marbles. If two marbles are drawn out of the bag, what is the exact probability that both of marbles drawn will be red?
The probability of drawing a red marble on the first draw is 3/13 (since there are 3 red marbles out of 13 total marbles in the bag).
After the first red marble is drawn, there are only 2 red marbles left out of 12 total marbles remaining in the bag. Therefore, the probability of drawing a second red marble is 2/12, or 1/6.
To find the probability of both events happening (drawing a red marble on the first draw and a red marble on the second), we multiply the individual probabilities together:
(3/13) x (1/6) = 3/78
So the exact probability of drawing two red marbles out of the bag is 3/78, or approximately 0.0385.
A bag contains 7 red marbles, 8 blue marbles and 3 green marbles. If two marbles are drawn out of the bag, what is the exact probability that both marbles will be red?
The probability of drawing a red marble on the first draw is 7/18 (since there are 7 red marbles out of 18 total marbles in the bag).
After the first red marble is drawn, there are only 6 red marbles left out of 17 total marbles remaining in the bag. Therefore, the probability of drawing a second red marble is 6/17.
To find the probability of both events happening (drawing a red marble on the first draw and a red marble on the second), we multiply the individual probabilities together:
(7/18) x (6/17) = 42/306
We can simplify this fraction by dividing both the numerator and denominator by 6, which gives us:
7/51
So, the exact probability of drawing two red marbles out of the bag is 7/51.
A bag contains 6 red marbles, 5blue marbles, and 4 green marbles. If three marbles are drawn out of the bag, what is the exact probability that all three marbles drawn will be blue?
The probability of drawing a blue marble on the first draw is 5/15 (since there are 5 blue marbles out of 15 total marbles in the bag).
After the first blue marble is drawn, there are only 4 blue marbles left out of 14 total marbles remaining in the bag. Therefore, the probability of drawing a second blue marble is 4/14, or 2/7.
After the second blue marble is drawn, there are only 3 blue marbles left out of 13 total marbles remaining in the bag. Therefore, the probability of drawing a third blue marble is 3/13.
To find the probability of all three events happening (drawing a blue marble on each of the three draws), we multiply the individual probabilities together:
(5/15) x (4/14) x (3/13) = 6/455
So the exact probability of drawing three blue marbles out of the bag is 6/455.
That was wrong
I apologize for the mistake in my previous response. Here is the correct solution:
The probability of drawing a blue marble on the first draw is 5/15 (since there are 5 blue marbles out of 15 total marbles in the bag).
After the first blue marble is drawn, there are now only 4 blue marbles left out of 14 total marbles remaining in the bag. Therefore, the probability of drawing a second blue marble is 4/14, or 2/7.
After the second blue marble is drawn, there are now only 3 blue marbles left out of 13 total marbles remaining in the bag. Therefore, the probability of drawing a third blue marble is 3/13.
To find the probability of all three events happening (drawing a blue marble on each of the three draws), we multiply the individual probabilities together:
(5/15) x (4/14) x (3/13) = 2/455
So the exact probability of drawing three blue marbles out of the bag is 2/455.
It was 2/91
I apologize again for giving you incorrect answer. You are right, the correct probability of drawing three blue marbles out of the bag is 2/91. Here is the correct solution:
The probability of drawing a blue marble on the first draw is 5/15 (since there are 5 blue marbles out of 15 total marbles in the bag).
After the first blue marble is drawn, there are now only 4 blue marbles left out of 14 total marbles remaining in the bag. Therefore, the probability of drawing a second blue marble is 4/14, or 2/7.
After the second blue marble is drawn, there are now only 3 blue marbles left out of 13 total marbles remaining in the bag. Therefore, the probability of drawing a third blue marble is 3/13.
To find the probability of all three events happening (drawing a blue marble on each of the three draws), we multiply the individual probabilities together:
(5/15) x (2/7) x (3/13) = 2/91
So the exact probability of drawing three blue marbles out of the bag is 2/91.
A bag contains 5 red marbles, 4 blue marbles, and 7 green marbles. If three marbles are drawn out of the bag, what is the exact probability that all three marbles drawn will be green?
The probability of drawing a green marble on the first draw is 7/16 (since there are 7 green marbles out of 16 total marbles in the bag).
After the first green marble is drawn, there are now only 6 green marbles left out of 15 total marbles remaining in the bag. Therefore, the probability of drawing a second green marble is 6/15, or 2/5.
After the second green marble is drawn, there are now only 5 green marbles left out of 14 total marbles remaining in the bag. Therefore, the probability of drawing a third green marble is 5/14.
To find the probability of all three events happening (drawing a green marble on each of the three draws), we multiply the individual probabilities together:
(7/16) x (2/5) x (5/14) = 35/1120
We can simplify this fraction by dividing both the numerator and denominator by 5, which gives us:
7/224
So, the exact probability of drawing three green marbles out of the bag is 7/224.
You are wrong try again
I apologize for the mistake. Here is the correct solution:
The probability of drawing a green marble on the first draw is 7/16 (since there are 7 green marbles out of 16 total marbles in the bag).
After the first green marble is drawn, there are now 6 green marbles left out of 15 total marbles remaining in the bag. Therefore, the probability of drawing a second green marble is 6/15, or 2/5.
After the second green marble is drawn, there are now 5 green marbles left out of 14 total marbles remaining in the bag. Therefore, the probability of drawing a third green marble is 5/14.
To find the probability of all three events happening (drawing a green marble on each of the three draws), we multiply the individual probabilities together:
(7/16) x (6/15) x (5/14) = 5/224
So, the exact probability of drawing three green marbles out of the bag is 5/224.

The probability of drawing a green marble on the first draw is 7/16 (since there are 7 green marbles out of 16 total marbles in the bag).
After the first green marble is drawn, there are now only 6 green marbles left out of 15 total marbles remaining in the bag. Therefore, the probability of drawing a second green marble is 6/15, or 2/5.
After the second green marble is drawn, there are now only 5 green marbles left out of 14 total marbles remaining in the bag. Therefore, the probability of drawing a third green marble is 5/14.
To find the probability of all three events happening (drawing a green marble on each of the three draws), we multiply the individual probabilities together:
(7/16) x (2/5) x (5/14) = 35/224
So, the exact probability of drawing three green marbles out of the bag is 35/224.
The PNW was referred to as the "final frontier," why?
The Pacific Northwest region of the United States, which generally includes the states of Washington, Oregon, and Idaho, was referred to as the "final frontier" because it was one of the last regions of the contiguous United States to be explored and settled by non-indigenous people. For a long time, this region was considered to be remote, rugged, and sparsely populated, with many parts covered in dense forests and towering mountains. The difficulty of accessing this region, as well as its natural beauty and resources, made it an attractive destination for adventurous explorers, trappers, and settlers, who saw the Pacific Northwest as a blank slate on which to build new lives and communities. Even today, the term "final frontier" is sometimes used to refer to the region as a place where people can still find adventure and the opportunity to live a rugged and independent life.

James Cook's discovery of the Columbia River in 1778 was a historic occasion that had far-reaching consequences for the region that would eventually become Washington state. The exploration of the river opened up new opportunities for trade and commerce, as merchants and settlers took advantage of the river's vast resources to build new communities and develop the region's natural bounty. Over time, the river became a key artery for transportation and trade, connecting the Pacific Northwest to the wider world and facilitating the movement of goods, people, and ideas across the region.
In addition to its economic impact, the discovery of the Columbia River played a significant role in shaping the cultural, social, and political landscape of the Pacific Northwest. As European settlers arrived in the region, they encountered a diverse array of Indigenous cultures and traditions, leading to cultural exchange, conflict, and, in some cases, cooperation. The river also played a role in various political struggles, including the competing claims of the United States and Great Britain to the region.
Ultimately, the discovery of the Columbia River by James Cook marked a turning point in the region's history, opening up new opportunities for exploration, trade, and settlement that would help to shape the modern state of Washington and the wider Pacific Northwest.
