The probability that 3 randomly selected people all have the same birthday, ignoring leap years, is calculated by considering that the first person can have any birthday, the second must have the same birthday as the first (1/365 chance), and the third must also match the first two (1/365 chance). Thus, the probability is (1/365) * (1/365) = 1/133,225 or approximately 0.00000751 when rounded to eight decimal places.
