The probability that a person who booked a flight will actually
show up is 0.95. If the airline books 104 people on a flight for
which the maximum capacity is 100, what is the probability that
there will be enough seats for everyone who shows up? Round your
answer to 3 decimal places.
At one point during the COVID-19 crisis, the probability that an
person who tested positive for the illness would infect another
person they came into contact with was 75% . Suppose on that day,
the infected person came into contact with 15 other people.
For each part below, show the formula set-up and round your
final answers to four decimal places.
a) The probability the ill person infected exactly 10 people out
of the 15.
b) the probability the ill...
A test is designed to detect cancer. If a person has cnacer,
then the probability that the test will detect it is .95; if the
person does not have cancer, the probability that the test will
erroneously indicate that he does have cancer is .1. Assume 15% of
the population who take the test have cancer. What is t he
probability that a person described by the test as not having
cancer really does have it?

has a probability of 80% of answering any particular question
correctly. Find the probability of answering between 70 and 80
questions, inclusive. (Assume independence, and round your answer
to four decimal places.)
