An urn contains 10 red and 8 white balls. One ball is drawn at random. Find the probability
that the ball drawn is white.
उत्तर
Total no of possible outcomes = 18 {10 red balls, 8 white balls}
E ⟶ event of drawing white ball
No. of favourable outcomes = 8 {8 white balls}
Probability, P(E) =`"No.of favorable outcomes"/"Total no.of possible outcomes"`
=818 =4/9
