their 90th birthday. In a graduating class of 759 high school
seniors, find the following probabilities. (Round your answers to
four decimal places.)
(a) 15 or more will live beyond their 90th birthday
(b) 30 or more will live beyond their 90th birthday
(c) between 25 and 35 will live beyond their 90th birthday
(d) more than 40 will live beyond their 90th birthday

Ocean fishing for billfish is very popular in the Cozumel region of
Mexico. In the Cozumel region about 47% of strikes (while trolling)
resulted in a catch. Suppose that on a given day a fleet of fishing
boats got a total of 27 strikes. Find the following probabilities.

Based on long experience, an airline found that about 6% of the
people making reservations on a flight from Miami to Denver do not
show up for the flight. Suppose the airline overbooks this flight
by selling 263 ticket reservations for an airplane with only 255
seats.(a) What is the probability that a person holding a
reservation will show up for the flight?
(b) Let n = 263 represent the number of ticket
reservations. Let r represent the number of people with
reservations who show up for the flight. What expression represents
the probability that a seat will be available for everyone who
shows up holding a reservation?
P(r ≥ 263)P(r ≤ 263) P(r ≥ 255)P(r ≤ 255
(c) Use the normal approximation to the binomial distribution and
part (b) to answer the following question: What is the probability
that a seat will be available for every person who shows up holding
a reservation? (Round your answer to four decimal
places.)
One environmental group did a study of recycling habits in a California community. It found that 74% of the aluminum cans sold in the area were recycled. (Use the normal approximation. Round your answers to four decimal places.)
(a) If 384 cans are sold today, what is the probability that 300
or more will be recycled?
(b) Of the 384 cans sold, what is the probability that between 260
and 300 will be recycled?
