Two cards were drawn, without replacement, from pack of 52 cards. What is the probability that they are both kings or both queens?
That sounds like a low probability. Can you explain how you got that answer?
Sure, there are four kings and four queens in a deck of 52 cards. So the probability of getting two kings is (4/52) x (3/51) = 1/221. Similarly, the probability of getting two queens is (4/52) x (3/51) = 1/221. So the probability of getting either two kings or two queens is 1/221 + 1/221 = 2/221 = 1/110.
