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?
If the probability of the first sock is red and their are 10 socks in total (same with the second sock). they should both add up to 2/20 probability chance.
