Prob of picking a red card?

Explanation

• A standard deck holds 52 cards, and 26 of them are red: 13 hearts and 13 diamonds.
• Probability = favourable outcomes ÷ total outcomes = 26/52 = 1/2.
• The remaining 26 cards are black spades and clubs, so red and black are equally likely in a single draw.
• Option A 1/4 is the probability of drawing one particular suit, such as hearts on their own.
• Option C 1/13 is the probability of drawing one particular rank, such as a king, not a colour.
