You randomly select a card from a 52-card deck. Find the probability of selecting a Queen or a King.

There are 4 Queens and 4 Kings in a 52-card deck. So, the total number of favorable outcomes is 4 + 4 = 8.

The total number of possible outcomes is 52.

Therefore, the probability of selecting a Queen or a King is 8/52 = 2/13.
