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

No, There are only a total of 18 marbles.

Hint: Simplify the fraction.

To find the probability of choosing a purple marble, we need to calculate the ratio of the number of favorable outcomes to the total number of possible outcomes.

In this case, the number of favorable outcomes (purple marbles) is 3, as given in the question.

The total number of possible outcomes is the sum of the marbles in the bag, which is 6 green + 4 red + 5 yellow + 3 purple = 18.

Therefore, the probability of choosing a purple marble is 3/18, which simplifies to 1/6.

So, the correct option would be A. 1/6.
