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 Red

Solution

Total no. of possible outcomes = 15

{5 black, 7 red & 3 white balls}

E ⟶ event of drawing red ball

No. of favorable outcomes = 7 {7 red balls}

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

P(E) =7/15
