Question

A bag contains 1 red, 1 yellow, 1 blue, and 1 green marble. What is the probability of choosing a green marble, not replacing it, and then choosing a red marble? StartFraction 1 over 16

Answer 1

Answer: 1/12

Explanation:

Answer 2

1/12

Explanation:

The probability of first choosing a green marble is 1/4, because there is one green and 4 total.

When you don't replace the green marble, the total number of marbles is now 3, and there is one red marble in the bag. So the second probability is 1/3.

These are independent events, so we multiply them together to get

1/4 * 1/3 = 1/12
