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 Black

Answer 1

Total no. of possible outcomes = 8 {3 red, 5 black}

Let E ⟶ event of drawing black ball.

No. favourable outcomes = 5 {5 black balls}

P(E) =`"No.of favorable outcomes"/"'Total no.of possible outcomes"`

P(E) = 5/8
