A raffle held by Mundane Products has collected 700 entries. They are giving away 40 TVs and 30 stereos. John bought 5 entries for the raffle.
What is the probability that John wins exactly one TV as well as exactly one stereo?
John just heard that the TVs are already decided and he has won exactly one of the 40 TVs. What is the probability that John will win at least one stereo in the remaining drawing?
