Hershey’s bars, and 2 Heath Bars.
a. Create a simulation for randomly selecting a Snicker’s bar.
b. Create a simulation for randomly selecting a Snicker’s and then a Heath
bar.

also a Krackle in the jar.
2. At the charity 5K run held last Saturday, 120 people participated.
a. Give a simulation which would represent Mary coming in first and John
coming in second.
b. Using the same scenario, how would the simulation change to represent
Mary coming in first, John second, and Elizabeth coming in third?
c. How would the simulation change if there were 100 runners with Mary
coming in first and John coming in second?
3. A basketball player makes free throws 1 out of every 4 times he is at the foul
line.
a. Create a simulation to represent a basketball player hitting free throws
on his first 2 times at the line in every game.
b. Change the simulation to represent the player making 1 out of every 8
times he is at the line where he still hits on his first two times at the line
in every game.
c. Change the simulation to represent making it on his first 3 times at the
line in every game if he hits 1 out of every 4 times he is at the foul line.
