    [SOLVED] card deck probability

    this isn't that advanced but here's the questions:

    we randomly pull 2 cards out of a standard deck of 52, with replacement.

    a) what is the probability that we pull a king first and then an ace?

    b) what is the probability that we pull a king and an ace?

    Pr(KA or AK) = (4/52)(4/51) + (4/52)(4/51) = ....
