Problem 1: There are 8 males and 12 females in a class. If one student is chosen at random, what is the probability a female student is selected?
Problem 2: From the class described in the previous question (8 males, 12 females) how many ways are there to line up 5 students (regardless of gender)?
Problem 3:The following college degrees were awarded at a
university in a recent academic year:
Bachelor’s Master’s Doctorate
Men: 307 138 84
Women: 542 126 68
If a degree is chosen at random, find the probability that it
is:
a) a bachelor’s degree
b) a doctorate OR a degree awarded to a man
c) NOT a master’s degree

asked to report their actual height and what they wished as their
ideal height. A 95% confidence interval for μd= average difference
