Question 1083037: Assume there are 365 days in a year.
What is the probability that ten students in a class have different birthdays?
What is the probability that at least ten students in a class share their birthday

To have a different birthday, it is
364/365*363/365*362/365*361/365*360/365*359/365*358/365*357/365*356/365*355/365=0.8589
I'm not sure if I understand the wording on the second part, but the probability that at least two have the same birthday would be the complement, or 0.1411.
