A bag contains 4 red, 5 black and 6 white balls. A ball is drawn from the bag at random. Find the probability that the ball drawn is Red or white
उत्तर
Total no. of possible outcomes = 15 {4 red, 5 black, 6 white balls}
E ⟶ event of drawing red or white ball
No. of favourable outcomes = 10 {4 red & 6 white}
Probability, P(E) =`"No.of favorable outcomes"/"Total no.of possible outcomes"`
P(E) =10/15 =2/3
