Answer 1

17/25

Explanation:

You need to add the probability of choosing a blue marble to the probability of choosing a yellow one.

The probability of choosing a blue marble is 10/25, since there are 10 blue ones, and 25 total.

The probability of choosing a yellow marble is 7/25.

10 + 7 = 17

17/25
