Each week Bob and three friends fromw ork pool their money together and buy 12 lottery tickets that are randomly and equally divided up among the group.

a) In lotto mania, the game played by Bob and his friends, 6 winning numbers are seletced by random sampling w/o replacement from a bin of balls numbered 1 through 30. A player wins if the 6 numbers on his/her ticket match at least 5 numbers from the six winning numbers (order is irrelevant). If you buy a single ticket, what is the probability that you will win something? ANS: 0.0002442
