4 people are to be chosen from 10 men and 12 women to form a
committee which contains at least two women. How many different
ways can the committee be formed? If, among the 10 men and 12

a.) A committee of five people is to be selected from a group of
11 people. Five of the 11 people are men and the rest are women. If
a committee is randomly selected, find the probability that the
committee has no men.
b.) Given a committee of 5 people, how many ways can we choose
one of these five people to be the chair of the committee and one
of these five people be chosen as the co-chair of...

Suppose that a random sample of 100 men between the ages of 25
and 54 was selected and it was found that 84 were currently
working. A similar sample of 100 women was selected and 70 were
working. Complete parts a and b below.
a. Using alphaequals 0.10?, can it be concluded that the proportion
of men in this age group who are working differs from the
proportion of women who are? working?

Conditional Probability
Activity 1: CHC Student Survey
Suppose a survey of 100 randomly selected CHC students resulted
in a sample of 60 male and 40 female students. Of the males, 2/3
graduated from a high school in Philadelphia, while the remainder
had high school diplomas from out-of-the-city. Of the females, 3/4
were from Philadelphia high schools. This information is
represented in the following contingency table:
Phila. HS
