comment Logic Puzzle: Determining Set Combinations
Correct. Once an element from a set has been used in an answer, it cannot be used in another answer. By "combination," I meant five elements, one from each set.

@Qiaochu: I see your point. It should be exponential, not multiplication. (1/365)^3 would be greater than (1/365)^50. Thanks for pointing out that error.

I multiplied by three because there are three people who share a birthday with another person.

I would like the probability of four people sharing a birthday.
