Drawing one card from a full deck, the probability it is a spade is 13 out of:
A40 cards
B52 cards
C13 cards
D26 cards
Answer & Solution
Correct answer: B. 52 cards
1. A full deck holds 52 cards in four equal suits.
2. Each suit therefore contains 13 cards.
3. So the probability is 13 out of 52 cards, one quarter.
