Suppose that the probability that a passenger will miss a flight is 0.0943. Airlines do not like flights with empty​ seats, but it is also not desirable to have overbooked flights because passengers must be​ "bumped" from the flight. Suppose that an airplane has a seating capacity of 58 passengers.

​(a) If 60 tickets are​ sold, what is the probability that 59 or 60 passengers show up for the flight resulting in an overbooked​ flight?

​(b) Suppose that 64 tickets are sold. What is the probability that a passenger will have to be​ "bumped"?

​(c) For a plane with seating capacity of 53 ​passengers, how many tickets may be sold to keep the probability of a passenger being​ "bumped" below

55​%?

What is the probability, p(A|B), where A is the roll of a “3” or a “4” on a fair die and B is the probability of tossing exactly two heads out of 4 tosses with a fair coin? It is assumed the rolls of the die and the tosses of the coins are independent. Provide your answer as a reduced fraction.

The probability of winning on a lot machine is 5%. If a person plays the machine 500 times, find the probability of winning 30 times. Use the normal approximation to the binomial distribution.

A travel survey of 1500 Americans reported an average of 7.5 nights stayed when they went on vacation. Find a point estimate of the population mean. If we can assume the population standard deviation is 0.8 night, find the 95% confidence interval for the true mean.

Suppose that the probability that a passenger will miss a flight is 0.0993. Airlines do not like flights with empty​ seats, but it is also not desirable to have overbooked flights because passengers must be​ "bumped" from the flight. Suppose that an airplane has a seating capacity of 50 passengers. ​(a) If 52 tickets are​ sold, what is the probability that 51 or 52 passengers show up for the flight resulting in an overbooked​ flight? ​(b) Suppose that 56 tickets are sold. What is the probability that a passenger will have to be​ "bumped"? ​(c) For a plane with seating capacity of 53 ​passengers, how many tickets may be sold to keep the probability of a passenger being​ "bumped" below 5​%?
