We are drawing two cards without replacement from a standard 52 card deck. Find the probability that we draw at least one queen.

OpenStudy (btaylor):

the probability of drawing 1 queen in 1 pick is 1/13. Since you have two chances, you get 1/13 + 1/13 = 2/13

OpenStudy (anonymous):

That's not right.

OpenStudy (anonymous):

The probability of getting at least one queen is the probability of getting a queen on the first draw plus the probability of getting something else on the first draw and a queen on the second. So the probability is: 1/13+48/51 * 4/51

OpenStudy (btaylor):

@Thomas9 the question requires AT LEAST ONE QUEEN, not exactly one queen.

OpenStudy (anonymous):

I'm correct, you can get two queens in my method, it's in the 1/13 term. To disprove your method: if you draw 14 cards you'd end up with a probability of 14/13. which is absurd.
