Question

You choose one card from a standard deck. What is the probability of selecting a Ace OR a Red card?Please write your anwer as a reduced fraction.

Answer 1

A standard deck has 52 cards

there are 26 red cards and 26 black cards

there are 4 aces in the deck

so the probability for an ace is 4/52

the probability of a red card is 26/52= 0.5

now adding both probabilities it gets

0.5 + 1/13
