Answer:

5/144

Step-by-step explanation:

Step one:

given data

sample space

15 white,

8 pink,

3 yellow, and

10 black golf balls

Sample size= 15+8+3+10= 36 golf balls

Step two:

1. first event

selecting a yellow ball= 3/36= 1/12

2. second event with a replacement on the first event

selecting a white ball= 15/36= 5/12

hence for the two events, the probability is

1/12*5/12

= 5/144
