Question
You have a standard deck of 52 playing cards. What is
the probability of drawing a red card (heart or diamond) from the deck?Solution
There are 26 red cards in a standard deck (13 hearts + 13 diamonds), and a total of 52 cards. Therefore, the probability of drawing a red card is: Probability = (Number of favorable outcomes) / (Total number of outcomes) Probability = 26 / 52 Probability = 0.5 or 50% Â
