Question

A bag contains 6 red marbles, 6 purple marbles, and 6 yellow marbles. What is the probability of randomly selecting a yellow marble from the bag?

Answer 1

1/3

Explanation:

The probability of selecting yellow is the number of yellow marbles / the total number of marbles.

There are 6+6+6 = 18 total marbles in the bag.

There are 6 yellow marbles in the bag.

So the probability of getting yellow is 6/18 = 1/3.
