The part I didn't get was:
"Since neither prisoner 1 or 2 knows which colour hat they have on, they
must BOTH be wearing red ones because, if 3 had a red hat on, prisoner
#2 would KNOW that he has a white one on"
I don't see why P1 and P2 must both be wearing red hats. Why can't they
both be wearing white hats? Or why can't P1 be wearing white and P2
red? Or vice versa?
