a) what is the probability that your bridge partner has exactly two aces, given that she has at least one ace?

I know that Pr(2 aces given >= 1 ace) = P(2A and >= 1A)/P(>=1A), but I don't know what these values are. What would be the probability of having at least 1 ace? I'm not sure how the cards are dealt and/or how many are held at a time
