Consider the following game: A player rolls two dice. If he rolls 7 or less then he loses the game. Otherwise, he selects at random as many cards from the full deck as the sum of the numbers that came up on the dice. The player wins if all four Aces are among the selected cards. (a) What is the winning probability for this game? (b) Someone tells that he played this game once and won. What is the probability that he rolled a sum of 10?
Suppose Emerson loses 26% of all checker games. (a) What is the probability that Emerson loses two checker games in a row? (b) What is the probability that Emerson loses five checker games in a row? (c) When events are independent, their complements are independent as well. Use this result to determine the probability that Emerson loses five checker games in a row, but does not lose six in a row. (a) The probability that Emerson loses two chockor
