Question

Rylee has a pack of 40 ballons. In the pack, there are 7 red, 12 green, 11 blue, and 10 yellow balloons. When grabbing a balloon, she expects to grab a yellow ballon of the time.

Answer 1

1/4

Explanation:

If she expects yellow, the probability of that happening is 10/40 = 1/4

So if she draws 4 balloons she should expect to get 1 yellow one.
