Question

If a card is chosen from a standard deck of cards, what is the probability of getting a five or a seven?

Answer 1

In a standard deck of cards, there are 4 fives and 4 sevens (one five and one seven of each suit).

The total number of cards in a standard deck is 52.

Therefore, the probability of getting a five or a seven would be (4 + 4) / 52 = 8 / 52 = 2 / 13.

So, the probability of getting a five or a seven is 2/13.
