Homework Equations
The Attempt at a Solution
Well I am not really sure what method I should use here??
but... the total number of solutions is surely 365n
but at least two?
maybe something along the lines...
P(365,2)
so
the probability is P(365,2)/365n
But I have a feeling I'm missing something, but I don't understand what?
