A draw contains 3 black socks and 2 white socks. A sock isdrawn at random and then replaced. Find each probability. p(2 black) p(black, then white) p(white, then black) p(2white)

1. PsyDAG

The probability of both/all events is determined by multiplying the probability of the individual events.

P(2black) = 3/5 * 3/5 = 9/15 = 3/5 = .6

Use the same process for the remaining probabilities.
