In Lotto 4-39, the lottery picks 4 numbers (without replacement) from 1 to 39. Before this drawing is done, you pick 4 numbers (without replacement) from 1 to 39. Find the probability that: a) None of my numbers are chosen B)exactly 2 are chosen For a) I figured out total number of possibilities 39C4, then I did 1/39C4 for the probability because I figured no numbers was just one possible combination. Where did I go wrong?
