Hi !

I have to give an maths-related presentation for my high school final exam, so i have a little puzzle for you.

How many people need to be in a group for the probability that at least two of them share the same birthday to be 50% or higher?

Please, don't try to calculate it (and if you already know don't tell it please). Tell me just what was your first thought. I would like to make a sort of poll to see whether the answer matches people’s intuition.

Thanks (and sorry for my bad english)
