If the second person is to have the same birthday, they only have one option for their birthday, so the probability is 1 365 hence, (2 people sharing the same birthday) = 365 365 x 1 365 = 1 365 q2. In fact, the diagram also helps us see that a solution is possible for any even number of people (greater than 4) because adding another pair of people simply adds another “spoke” to. So, we’ll give him the probability of 363/365.
