Question

A drawer contains 8 red socks, 6

white socks, and 4 blue socks. Without
looking, you draw out a sock, return
it and draw out a second sock. What is
the probability that the first sock is
white and the second sock is blue?.

simplest form

Answer 1

2/27

Explanation:

First probability = 6/18 = 1/3

second probability = 4/18 = 2/9 (in this case the number of socks remains the same because we returned the first one)

Final probability = 1/3 * 2/9 = 2/27
