Question

When a card is selected at random from a pack of cards, find the probability that it is a king.

Answer 1

There are 52 cards in a pack of cards.

So, a card can be selected in 52 ways.

Now, there are 4 kings ( one in each suit ) in the pack.

So, a king can be selected in 4 ways.

Therefore, required probability = $\frac{4}{52}=\frac{1}{13}$
