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?

A.1/6
B.6/18
C.3/20
D.1/9

My choice is A

6+4+5+3 = 18

3/18 = 1/6 A

I agree.

Thank you....both

To find the probability of choosing a purple marble, we need to determine the total number of marbles and the number of purple marbles in the bag.

In this case, the bag contains 6 green marbles, 4 red marbles, 5 yellow marbles, and 3 purple marbles. Therefore, the total number of marbles in the bag is 6 + 4 + 5 + 3 = 18.

Since we want to find the probability of choosing a purple marble, we can see that there are 3 purple marbles in the bag.

To calculate the probability, we use the formula:

Probability = Number of favorable outcomes / Total number of possible outcomes

In this case, the favorable outcome is choosing a purple marble, and the total number of possible outcomes is the total number of marbles in the bag.

So, the probability of choosing a purple marble would be:

Probability = 3 (number of purple marbles) / 18 (total number of marbles)

Simplifying the fraction, we get:

Probability = 1/6

Therefore, the correct answer is A) 1/6.
