A bag contains 3redballs,4blue balls 5white balls and 6black balls.a ball is picked at random what is the probability that it is either (a)blue,white or black with formula

Answer 1

Number of blue balls + Number of white balls + Number of black balls = 4 + 5 + 6 = 15
Total number of balls in the bag = 3 + 4 + 5 + 6 = 18

Probability = (Number of blue balls + Number of white balls + Number of black balls) / Total number of balls
Probability = 15 / 18
Probability = 5 / 6

Therefore, the probability that a ball picked at random is either blue, white, or black is 5/6.
