Question

A card is drawn at random from a well-shued pack of 52 cards. Find the probability of getting
(i) a red king.
(ii) a queen or a jack

Answer 1

Answer:

Probability of getting a king = P(A) = 452

Probability of getting a red card = P(B) = 2652

Probability of getting a red coloured king card = P(AB) = 256

∴ Required probability = P(A)+P(B)-P(AB) = (4+26−2)52=713

Answer 2

(1)p(red king)=2/52=1/26
(2)p(queen or jack)=8/52=2/13
