probability of what?
sandra
  • sandra
I think this is a conditional probability problem - that is P(A|B) with A = probability of a 2 given that the number is even
sandra
  • sandra
so intuitively, if the number is even, there are 10 even numbers between 1 and 20 inclusive

and one of those even numbers is 2

the definition of P(A|B) = P(A and B)/ P(B)
