प्रश्न
A card is drawn at random from a well-shuffled pack of 52 playing cards. Find the probability of the events that the card drawn is :
(a) a king (b) a face card.
उत्तर
A total number of all possible outcomes = 52.
i.e,. n(S) = 52
a. Let A be the favourable outcomes of getting a king, Then
i.e.,n(A) = 4
Therefore,
⇒ p(A) = `(n(A))/(n(S)) =4/52 = 1/13`.
b. Let B be the favourable outcomes of getting a face card, then
i.e., n(B) = 12
Therefore,
⇒ P(A) = `(n(B))/(n(s)) = 12/52 = 3/13`.
