Question

A drawer contains 4 red socks, 3 white socks, and 3 blue socks. Without looking, you select a sock at random, replace it, and select a second sock at random. What is the probability that the first sock is blue and the second sock is red?

Answer 1

A: 3/5
B: 7/20
C: 3/25
D: 7/100

Answer 2

C: 3/25
P (blue) = 3/10
P ( red) = 4/10 ( with replacement)
=> P (blue then red) = 3/10 * 4/10
= 12/100 = 3/25
