The television show Lost has been successful for many years. That show recently had a share of 24, meaning that among the TV sets in use, 24% were tuned to Lost. Assume that an advertiser wants to verify that 24% share value by conducting its own survey, and a pilot survey begins with 15 households have TV sets in use at the time of a Lost broadcast.Find the probability that none of the households are tuned to Lost.P(none) = Find the probability that at least one household is tuned to Lost.P(at least one) = Find the probability that at most one household is tuned to Lost.P(at most one) = If at most one household is tuned to Lost, does it appear that the 24% share value is wrong? (Hint: Is the occurrence of at most one household tuned to Lost unusual?) yes, it is wrong no, it is not wrong

Your friend Phil, asks you what you think about a new scratch-off lottery game. It costs $10 to play this game, There are two outcomes for the game (win, lose) and the probability that a player wins a game is 60%. A win results in $15, for a net win of $5 ($15 minus the $10 paid to play). The probability distribution for x� (the amount of money a player wins or loses) in a single game is as follows:
