No. of red balls = 75

No. of green balls =25

No. of blue balls = 90

Total no. of balls = 190

P ( not a blue ball) = 100/190

= 10/19

hope this answer will be helpful ^_^

Step-by-step explanation:

the probability of not finding the blue ball = 1 - the probabililty of finding the blue ball

therefore,

the probability of finding the blue ball = (1/75×25×90)

therefore, the probability of not finding the blue ball should be

1 - (1/75×25×90) = (75×25×90 -1)/75×25×90
