Attn mathmaticians: what is probability of Ace appearing?

Can any of you mathmaticians tell me how to calculate the odds of a particular card appearing, say an Ace, at least once if you deal out n cards?

Re: Attn mathmaticians: what is probability of Ace appearing?

1 minus the probability of it not occuring at all, which is 1 - (48/52)*(47/51)*(46/50)*...
*(48-n+1)/(52-n+1)

or 1 - C(48,n)/C(52,n) = 1 - 48!(52-n)!/[52!(48-n)!] same as above.
