Question
If from a pack of 52 playing cards, 1 card is drawn at
random. What is the probability that it is either a King, Queen or a Jack?Solution
P(E) = (⁴C₁ + ⁴C₁ + ⁴C₁)/(⁵²C₁) = (4+4+4)/52 = 12/52 = 3/13 Simplified Solution: Total Cards = 52 Number of kings in a deck = 4; P(getting a King) = 4/52 = 1/13 Similarly, P(getting a Queen) = 1/13 P (getting a Jack) =1/13 P (King or Queen or Jack) = 1/13 + 1/13 + 1/13 = 3/13
