Question

A bag contains 3 red balls and 5 black balls. A ball is drawn at random from the bag. What is the probability that the ball drawn is (i) red? (ii) not red ? Select the correct answer from above options

Answer 1

A bag contains 3 red balls, 5 black balls. Totally there are 8 balls. ∴ n(S) = 8 i) Possibility that the red ball drawn, n(E) = 3 ∴ Probability, P(E) = n(E) n(S) = 3 8 (ii) Possibility that the 1 black ball drwn is n(F) = 5 ∴ Probability, P(F) = n(F) n(S) = 5 8
