A and B are
disjoint. What is the
P(A or B)?
You have a bag of 20 marbles. Twelve of the marbles are green and eight of the marbles are yellow.
2 You draw three marbles out of the bag without replacement. What is the probability that all three
of the marbles will be yellow? Is this a Bernoulli trial or not?

At many airports, a traveler entering the U.S. is sent randomly to one of several stations where her
4passport and visa are checked. If each of the 22 stations is equally likely, what is the probability that a traveler will be
sent to Station 2? What model would you use to find the probability?
Don't know?
A study found that 65% of MBA Bernoulli
students admit to cheating. A business
school dean surveys all the students in
the graduating class and gets
responses in which
cheating was admitted by 330 of 550
students. Is this a Bernoulli trial or not?
College students are a major target for Bernoulli
advertisements for credit cards. At a
university, 91% of students surveyed said
that they opened a new credit card
account within the past year. If that
percentage is accurate, how many
students would you expect to survey
before finding one who had not opened
a new account in the past year?
At the airport entry sites, a computer is Bernoulli
used to randomly decide whether a
traveler's baggage should be opened
for inspection. The chance of being
selected is 14%. What is your chance of
having your baggage opened? Is this a
Bernoulli trial or not?
You have a bag of 20 marbles. Twelve of Not Bernoulli
the marbles are green and eight of the
marbles are yellow. You draw three
marbles out of the bag without
replacement. What is the probability
that all three of the marbles will be
yellow? Is this a Bernoulli trial or not?
A city council of 6 Republicans and 14 Not Bernoulli
Democrats picks a committee of 3 people
at random. What is the probability that
they choose all Republicans for the
committee? Is this a Bernoulli trial or not?
Suppose the probability of a dropped Binomial
call is 0.02. What is the probability that
2 out of the next 20 calls placed on a
cell phone will be dropped? What
model
would you use to find the probability?
