You have a standard deck of 52 cards. you pick one card from the deck and then , without putting the first card back , pick a second card . what is the probability that both cards will be 9s? ?

there are 4 9's in a deck

 so first pick = 4/52 reduces to 1/13

second pick there would be 3 9's left and 51 cards so it would be 3/51 reduces to 1/17

probability of both happening = 1/13 * 1/17 = 1/221 (fraction form)

 if you need it in decimal it = 1/221 = 0.00452, rounded to 0.005
