A bag contains 8 red, 2 black and 7 white balls. One ball is drawn at random. The probability that the ball drawn is not white is
1017
Total number of balls
= No. of red balls + No. of black balls + No. of white balls = 17
Number of white balls = 7
⇒ P (getting white ball) = 717
⇒ P (not white)=1 - P(getting white balls) = 1−717 =1017
