there are 13 clubs in a standard 52 card deck. The first time you draw a club the odds of doing it are
13/52 = 1/4
The second time you draw a club, the number of clubs have gone down by 1 and the number of cards in the deck have also gone down by 1.
So this time the odds are12/51
The probability of both happening, one after the other without replacement is
1/4 * 12/51 = (1*12)/(4*51) = 12/204 = 3/51 = 1/17
1/17 = 0.0588
