Question

jerry has 4 black socks, 4 blue socks, and 2 white socks in a drawer. He reaches in at random and chooses a sick, does not replace it, and then chooses another. What is the probability he chooses 2 blue socks?

Answer 1

p(1st sock blue) = 4 / 10

p(2nd sock blue) = 3 / 9

p(2 blue socks) = 4/10 * 3/9
