Suppose two people are randomly selected from a class of 30 students. What is the probability that they have the same birthday? Round your answer to 3 significant digits
Required probability = P(two randomly selected people have the same birthday)
Now, the probability of the 1st person taking birth on any day of the year is 1. So, the probability of the 2nd person having same birthday as the 1st would be
So, Required probability =
