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.
