Default Re: A very simple problem

When we read the post we were assuming he wanted the probability of a specific one of his two cards being dealt again, you are answering the probability that either or both of his two cards are dealt again.

There is a small error in your answer.

P(a or b)=P(a)+P(b)-P(a and b) this is correct.

Your answer is P(a)+P(b/a)-P(a and b)

Your terms should be 2/52+2/52-(2/52*1/51) you figure the probability of hitting either of your two cards irrespective of each card. I don't have much time to explain in detail maybe someone else will.
