Question

A bag contains 6 red, 8 black and 4 white balls. A ball is drawn at random. What is the probability that ball drawn is not black?

Answer 1

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 = \(\frac{Total\,number\,of\,non\,black\,balls}{Total\,number\,of\,balls}\) = \(\frac{10}{18}=\frac{5}{9}\)
