Read this thread - this time you have a multinomial distribution with n = 13 and pr(heart) = pr(spade) = pr(diamond) = pr(club) = 1/4.

If the choosing is done without replacement, the pmf will be a multivariate hypergeometric distribution:
where h + d + c + s = 13.
You could also build in the h + d + c + s = 13 restriction and write it as:
