Question

If a card is drawn at random from a pack of 52 playing cards, then the probability that it is either king or spade is

• A. 4/13
• B. 2/13
• C. 1/13
• D. 3/13

Answer 1

Answer: (A)

4/13

Answer 2

n(S) = ⁵²C₁ = 52

n(5) = 4 + 13 – 1 = 16

p(5) = $\frac { 16 } { 52 } = \frac { 4 } { 13 }$.
