You go to a party with 500 guests. What is the probability that exactly one other guest has the same birthday as you? Calculate this exactly and also approximately by using the Poisson PMF. (For simplicity. exclude birthdays on February 29.)

Step 1
We need to find the probability that exactly one out of 500 guests at a party shares the same birthday as you. We are excluding February 29, so there are 365 possible birthdays. Show more…

You are in a certain zoom session with a total of 500 attendees, including you. What is the probability that exactly one other person has the same birthday as you? (Ignore the year, and February 29.) First, compute the exact probability using binomial PMF; then, compute an approximation using Poisson PMF.

Use the theoretical method to determine the probability of the following event: Sharing a birthday with another person when you both have birthdays in February (not born on a leap year). (Type an integer or a simplified fraction.)

Problem 50. The birthday problem. Consider n people who are attending a party. We assume that every person has an equal probability of being born on any day during the year, independent of everyone else, and ignore the additional complication presented by leap years (i.e., assume that nobody is born on February 29). What is the probability that each person has a distinct birthday?
