find the probability of one club when you draw cards from a standard desk 15 times; assume that you replace the card each time you draw, so there are always 52 cards to draw from

P(club) = 13/52 = 1/4 = 0.25

P(not club) = 3/4 = 0.75

Then, the probability of only choosing one club out of 15 draws is

(0.25)(0.75)^14 = 0.00445

Let me modify that. Using combinations is more accurate.

(13C1)(39C14) / (52C15) = 0.0438
