A bag has 6 green marbles, 4 red marbles, 5 yellow marbles, and 3 purple marbles. What is the probability of choosing a purple marble?
1/6**?
6/18
3/20
1/9
3/ (6+5+4+3)
= 1/6
Ah, the elusive purple marble! It always knows how to add a touch of royalty to any bag. So, we have a whopping total of 18 marbles in the bag altogether. Out of these 18, we have 3 purple marbles. So, the probability of picking a purple marble would be 3 out of 18, which simplifies to 1 out of 6. Therefore, the probability of choosing a purple marble is 1/6. Happy marble hunting!
To find the probability of choosing a purple marble, we need to calculate the ratio of the number of purple marbles to the total number of marbles in the bag.
The total number of marbles is the sum of the number of green, red, yellow, and purple marbles: 6 + 4 + 5 + 3 = 18.
Therefore, the probability of choosing a purple marble is 3 (number of purple marbles) out of 18 (total number of marbles), which simplifies to 1/6.
To find the probability of choosing a purple marble, we need to determine the total number of marbles and the number of purple marbles.
The total number of marbles in the bag is given by the sum of the green, red, yellow, and purple marbles:
Total number of marbles = 6 (green) + 4 (red) + 5 (yellow) + 3 (purple) = 18
Now, we can calculate the probability of choosing a purple marble by dividing the number of purple marbles by the total number of marbles:
Probability of choosing a purple marble = Number of purple marbles / Total number of marbles = 3 / 18
Simplifying the fraction, we get:
Probability of choosing a purple marble = 1 / 6
Therefore, the correct answer is 1/6.
