If the sum of the dice is either a 2, 3, or 12, the player loses; if the sum is either a 7 or an 11, he or she wins. If the outcome is anything else, the player continues to roll the dice until he or she rolls either the initial outcome or a 7. If the 7 comes first, the player loses; whereas if the initial outcome reoccurs before the 7, the player wins. Compute the probability of a player winning at craps. Hint : Let g G denote the event that the initial outcome is i and the player wins. The desired probability is ∑ ¡(g G ) ¢£ G¤£ . To compute ¡(g G ), define the events g G,¥ to be the event that the initial sum is i and the player wins on the n th roll. Argue that ¡(g G ) = ∑ ¡¦g G,¥ § ∞ ¥¤¢ . 2. We have a stick of 9 consecutive parts. Each part is painted red or white. If none of the neighboring parts are painted white, how We have a stick of 9 consecutive parts....
