Probability is traditionally considered one of the most difficult areas of mathematics, since probabilistic arguments often come up with apparently paradoxical or counterintuitive results. Examples include the Monty Hall paradox and the birthday problem. Probability can be loosely defined as the chance that an event will happen. There are several ways to approach this problem. One uses inclusion-exclusion, but there is also another, slightly simpler, solution. First, the inclusion-exclusion solution.
