The correct answer for the odds of getting at least one club by picking cards (with replacement) 11 times is 1 - (3/4)^11 = 1 - .04787 = .95213
==============================================================

Find the probability of at least one club when you draw cards from a standard deck 11 times; assume that you replace the card each time you draw , so there are always 52 cards to draw from.

Did you want a refund?
