Question 3
3.
An ice cream shop offers 40 different flavors. To simulate the most commonly chosen flavor, you could write the name of each flavor on a piece of paper and put it in a bag. Draw from the bag 100 times, and see which flavor is chosen the most.
Why is this simulation a bad way to figure out the most commonly chosen flavor?
