Suppose that the airline overbooks this flight by selling 226 ticket reservations for an airplane with only 219 seats. Let n = 226 represent the number of ticket reservations. Let r represent the number of people with reservations who show up for the flight. Which expression represents the probability that a seat will be available for everyone who shows up holding a reservation: Expression I : P(r ≥ 226) Expression II : P(r ≥ 219) Expression III : P(r ≤ 226) Expression IV : P(r ≤ 219) Expression V : P(r = 219) a. Expression II b. Expression III c. Expression I d. Expression V e. Expression IVJosé plays basketball. He makes free throw shots 43% of the time. José must now attempt two free throws. The probability that José makes the second free throw given that he made the first is 0.49. Is José's first free throw shot independent of his second free throw shot? There is not enough information to determine whether or not the two free throws are independent of each other. The two free throws are dependent on each other. O The two free throws are independent of each other. What is the probability that José makes both free throws? Round your answer to three decimal places.
