that's a binomial n=2, p=5/8
(if you do it this without replacement it's a hypergeometric)
I am trying to do this problem and I have the answer key of course to it. But I can't quite figure out how to get there if someone could help me out.
An urn holds 5 white and 3 black marbles. If 2 marbles are to be drawn at random with replacement and X denotes the number of white marbles, find the probability distribution for X.
Thanks for any help.
