2.) Air America has a policy of routinely overbooking flights, because past experience shows that some passengers fail to show. The random variable X represents the number of passengers who cannot be boarded because there are more passengers than seats. X 3 4 P(X) 0.815 0.113 0.057 0.009 0.006 a.) Construct the graph of the probability distribution. b.) If a flight is chosen at random, what is the probability that at least 3 passengers cannot be boarded? c.) If a flight is chosen at random, what is the probability that no more than 2 cannot be boarded? passengers d.) Find the mean number of passengers that cannot be boarded. e.) Find the standard deviation of the number of passengers that cannot be boarded.
