The answer is B) 2/13.

An easy way to figure this out is to find what the unsimplified probability would be:

Since there are 8 kings and queens in total, the number is:

8/52

But, since these are both even numbers, they can be simplified.

1/4 x 8 = 2

1/4 x 52 = 13

2/13

Since 13 is a prime number, the answer cannot be simplified anymore.
