1. Express the indicated degree of likelihood as a probability value.
"There is a 40% chance of rain."
2. Find the indicated probability
A bag contain 6 red marbles, 3 blue marbles, and 7 green marbles. If a marble is randomly selected from the bag, what is the probability that it is blue. Is the answer 3/16?
Your answers to both questions seem correct. However, I do not know what the "indicated degree of likelihood" was in 1.
I hope this helps. Thanks for asking.
1. To express the indicated degree of likelihood as a probability value, you simply convert the given percentage into a decimal. In this case, if the statement is "There is a 40% chance of rain," the probability value would be 0.4.
2. To find the probability of selecting a blue marble from the bag, we can use the formula:
Probability of an event = Number of favorable outcomes / Total number of possible outcomes
In this case, the number of favorable outcomes (blue marbles) is 3, and the total number of possible outcomes (total marbles) is 6 + 3 + 7 = 16.
Therefore, the probability of selecting a blue marble is:
Probability of selecting a blue marble = 3 / 16
So yes, the answer is 3/16.
1. To express the indicated degree of likelihood as a probability value, we simply convert the percentage into a decimal. Therefore, "There is a 40% chance of rain" can be expressed as a probability value of 0.40 or 40/100.
2. To find the probability of selecting a blue marble, we need to calculate the ratio of the number of blue marbles to the total number of marbles in the bag.
The total number of marbles in the bag is 6 (red) + 3 (blue) + 7 (green) = 16 marbles.
The probability of selecting a blue marble is therefore 3 (number of blue marbles) divided by 16 (total number of marbles), which simplifies to 3/16.
So, your answer of 3/16 is correct.
