A stack of cards contains 5 hearts numbered 1 through 5, and 8 clubs numbered 1 through 8. If two cards are drawn at random without replacement, what is the probability of drawing a club on the first draw and a club on the second draw?

13 = 100%
8 = 61,53846153846154%
5 = 38,46153846153846%
12 = 100%
7 = 58,33333333333333%
5 = 41,66666666666667%
61,53846153846154 x 58,33333333333333% = 35,8974358974359%
I might be entirely wrong and too stoned to do math xP

I think I understand what you're asking, not sure.
If there are 13 cards with 8 clubs, your chance of drawing a club on the first pick is 8/13 or 61.5%.
On the second pick there are 12 cards and 7 clubs so your chance of drawing a club is 7/12 or 58.3%.
P.S. There is no 1 of clubs or hearts unless you're refering to an ace.
