Counting, Probability, and the Birthday Problem

[@georgetzathas9002]

It's a shame that this hasn't gone viral like other math teaching videos. It's up there with the best in terms of quality, communication and clarity. It makes harder concepts easy to digest as every good teaching video should. Good job!

The birthday problem is always fun. Imagine that it was any r people. So the probability of no match then it would be P(no match)= [(365)(364) ... (365-r+1)]/365^r. Then the probability of at least 2 matches would be 1-P(no match)

[@pensivenincompoop2016]

Extend this so that the minimum number of people is required to have a 50% probability that at least 2 people match.

Extend this to 3 people and you won't have so much fun.
