A card is drawn from a well-shuffled standard deck of 52 cards. The probability of drawing a KING is
A$1/52$
B$1/26$
C$1/13$
D$1/4$
Answer & Solution
Correct answer: C. $1/13$
1. Standard deck: 52 cards, with 4 KINGS (one of each suit — hearts, diamonds, clubs, spades).
2. Sample space: $|S| = 52$ (each card equally likely).
3. Event 'king': $|E| = 4$.
4. $P(\text{king}) = 4/52 = 1/13$.
5. Option A is the probability of ONE specific card. Option B is for $|E| = 2$. Option D is the probability of a specific SUIT, not a king.
