. A bag contains 8 red, 6 white and 4 black balls. A ball is drawn a random from the bag. Find the probability that the drawn ball is


1. red or white

2. not black

3. neither white nor black

Best Answer

Total number of balls in bag = 8+6+4 = 18

1. red or white balls 

Total number of red and white balls = 6+8 = 14

Probability to drawn red or white = 14/18=7/9

2.Not black balls 

Total number of Black balls = 4

Probability to drawn black balls = 4/18=2/9

Probability to drawn not a black balls = 1-2/9 = 7/9

3.Neither white nor black

Total number of balls in bag = 18

White and black = 10

Neither white nor black = 18-10 = 8

Probability to drawn neither white nor black = 8/18 = 4/9
