Best answer

Total numbers of red balls = 6

Number of black balls = 8

Number of white balls = 4

Total number of non-red balls = 6 + 8 + 4 = 18

Number of non-black balls are = 6 + 4 = 10

Probability of getting a non-black ball is = Total number of non-black balls/Total number of balls

= 10/18

= 5/9

∴ Probability of getting a non-black ball is 5/9
