You randomly select one card from a 52-card deck. Find the probability of selecting an ace or a 9?

Solution:

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

Number of cards in a deck = 52

We have to find the probability of selecting an ace or a 9

We know that there are 4 aces and 4 9’s

So when there are 4 aces the probability = 4/52 = 1/13

When there are 4 9’s the probability = 4/52 = 1/13

If both aces and 9’s are together

P (ace or 9) = 8/52 = 2/13

Therefore, the probability of selecting an ace or a 9 is 2/13.

Summary:

You randomly select one card from a 52-card deck. The probability of selecting an ace or a 9 is 2/13.
