Q:
# A drawer contains 12 white socks and 8 black socks. You randomly choose 1 sock and do not replace it. Then you randomly choose another sock.Event A: The first sock is white.Event B: The second sock is white.Find the probability that both events A and B will occur. Round your answer to the nearest tenth.

Accepted Solution

A:

So in event A the probability will be 12/20, which is 3/5. In event B the probability will be 11/19. Multiplying these probabilities we get the probability of both occuring, which is (11*3)/(5*19)=33/95
