Ok so I think its asking for a binomial distribution of B(20, 1/52)

Would this be the probability function of X?

Also the range space of X is asked in a lot of these questions, but I've no idea on how to calculate it. I thought it was the codomain, so perhaps it's

20C0 * (1/52)^0 * (51/52)^20 = 0.678

20C20 * (1/52)^20 * (51/52)^0 = 4.79*10^-35

As the range. But it seems a little wrong :P

Any help is appreciated as my exam is tomorow!

Thx
