Probability problem - birthdays

Homework Statement

44. What is the probability that at least two people in your class (assume a class of 30 students) have the same birthday?

I'm not sure, to be honest.

I was helping out my roommate with his probability homework, and this question came up. I'm not sure how to answer it. How is this done?

Ahaha... I did not know there was a Wikipedia article on what seemed to me to be just an unusually difficult homework problem. Thanks!
