9. Ms. Affeldt has 167 students on her attendance at some

and 29 students are in her study hall. Of the Algebra 2
students, 8 of them are lucky enough to have study hall
with Ms. Affeldt. What’s the probability that a randomly
selected student would be a non-Alg 2 student or would be
in study hall with Ms. Affeldt?
13. While working at the A&W, I was one my bosses’
favorite employees (shocking, I know). All 10 employees
were told that we were in the running to win ‘Employee of
the Year’ and that there would also be an award for 1st
runner-up and one for 2nd runner-up. If the awards were
selected at random, how many different ways could the
three awards be given out?
10. The best place to get a cyclone is at the A&W in
Fosston, MN (former employer of the teenage Ms. Affeldt).
Let’s say there are currently 3 ice-cream flavors, 4 syrup

choose 1 of each of the above, how many different
cyclones can be made?

least two of the students randomly select the same outfit
for Addison?

if there were 12 flavors? How many different options do I
have? (Think about if order matters … take your opinion
out of it!)
15. Billy Bob is still playing Yahtzee and is curious what the
probability of rolling 5 of a kind on the first roll would be?
This makes him further curious as to what the probability
of rolling five 2’s would be?
12. Explain the difference between inclusive events and
mutually exclusive events. Which questions on this
worksheet would be an example of each?
16. Explain the difference between a permutation and a
