Chance Challenge - Probability

What is the probability of getting a club or an ace when randomly choose a card from a card deck of English?

A) 9 / 52

B) 10/52

C)

12/52 D) 16/52

E) 17/52

Answer: As events: A: "Get a club" and B "to get an ace" are NOT mutually exclusive, we proceed as follows:

P (getting a club or an ace) =

= P (getting a shamrock) + P (getting Ace) - P (get a club and an ace)

P (getting a shamrock) = 13/52

P (getting an ace) = 4 / 52

P (get a club and an ace ) = 1 / 52

P (getting a club or an ace) = 13/52 + 4 / 52 - 1 / 52 = 16/52; Alternative D)
