3) A card is drawn at random from a pack of well-shuffled 52 playing cards. Find the probability that
the card drawn is i) an ace ii) a spade.
Solution : S is the sample space
..n(S) =D
(There are 52 cards)
i) Let A be the event that the card drawn is an ace. There are four suits, Spade, Heart, Diamond and
Club. Each suit has one ace.
.. n(A) = { }
P(A) =
n(A)
n(S)
38
ii) Let B be the event that the card drawn is a spade. There are 13 cards in the suit of spade. One
spade can be drawn out of 13 spade cards in 13 ways.
.. n(B) = O
