You’ve likely had to determine the likelihood of simple events occurring, also known as probability. The following problems take it a step further and combine these ideas with combinatorics, a fancy way to describe the different potential arrangements of objects.
Remember that the probability of an event occurring is the number of ways we can complete the event divided by the total number of events that could happen.
