A bin contains seven red chips, nine green chips, three yellow chips, and six blue chips. Find each probability. drawing a yellow chip, replacing it, and choosing a blue chip.

We will use the Multiplication Rule of Probability to find the answer.

This rule states that to find the intersection of two events, multiply them together.

First find the probability of drawing a yellow chip. Do this by creating a fraction.

Probability of drawing a yellow chip:

3 <— 3 yellow chips
—
25 <— 25 total chips

Then find the probability of drawing a blue chip:

6 <— 6 blue chips
—
25 (still 25 as you put the yellow chip back in)

Now that we have the two probabilities multiply them together.

3/25 * 6/25 = 18/625 = about 2.8% chance
