You randomly select a card from a 52-card deck. Find the probability of selecting a 5 or a King.
There are 4 kings and 4 fives in a 52-card deck, since there is one king and one five in each suit.
Therefore, the total number of cards that are either a king or a five is 4 + 4 = 8.
The probability of selecting a 5 or a king is the number of cards that are a 5 or a king divided by the total number of cards in the deck, which is 8/52 = 2/13.
Therefore, the probability of selecting a 5 or a king is 2/13 or approximately 0.154.
