# A Bag Contains 5 Black, 7 Red and 3 White Balls. a Ball is Drawn from the Bag at Random. Find the Probability that the Ball Drawn Is Black Or White - Mathematics

A bag contains 5 black, 7 red and 3 white balls. A ball is drawn from the bag at random. Find the probability that the ball drawn is black or white

#### Solution

Total no. of possible outcomes = 15{5 black, 7 red & 3 white balls}

E ⟶ event of drawing black or white

No. of favourable outcomes = 8 {5 black & 3 white}

Probability, P(E) ="No.of favorable outcomes"/"Total no.of possible outcomes"

P(E) =8/15
