If a card is drawn from a well shuffled pack of cards, the probability of drawing a spade or a king is ?
Choose the correct answer:
A) 4/17
B) 4/18
C) 4/76
D) 4/13
E) 4/29
P(SᴜK)   = P(S) + P(K) - P(S∩K), where S denotes spade and K denotes king.   P(SᴜK)   = 13/52 + 4/52 - 1/52   = 4/13   Answer: 4/13
