Question

There are 4 queens in a standard deck of 52 CARDS. You pick one card at random. What is the probablity of not picking a queen?

Answer 1

Find the number of cards that are not queens by subtracting 4 from 52, which equals 48. So 48 cards out of 52 cards are not queens. This can be written as 48/52. Simplify this fraction. (48/4 / 52/4) = 12/13. The probability of not picking a queen is 12/13. Another, simpler, way to solve it is this: if you know there are 13 suites in a deck of cards, excluding one suite, in this case queens, will give you 12 out of 13 suites left that are not that suite.
