Answer:

9/23

Step-by-step explanation:

Of the 23 students, 9 play both baseball and basketball. The probability of choosing one of those is 9/23.

___

Let A represent basketball, and B represent baseball. Then ...

P(A or B) = P(A) +P(B) -P(A and B)

Since 8 students play neither sport, we have ...

1 -8/23 = 11/23 +13/23 -P(A and B)

15/23 = 24/23 -P(A and B)

P(A and B) = (24 -15)/23

P(A and B) = 9/23
