Question 1072190: A drawer of loose socks contains 2 red socks, 2 green socks, and 6 white socks. Which best describes how to determine the probability of pulling out a white sock, not replacing it, and pulling out another white sock?
You can put this solution on YOUR website! 10 socks, 6 of them white
6/10 is probability of pulling out a white sock.
Then 5 of 9 socks left are white, so the probability of a second white sock is 5/9.
the joint probability is their product, or 1/3 (30/90).
