Question

A bag contains $2$ blue, $4$ yellow and $3$ red balls, what is the probability of getting a ball at random which is not yellow?

• A. $\frac{5}{9}$
• B. $\frac{4}{9}$
• C. $\frac{2}{9}$
• D. $\frac{1}{9}$

Answer 1

The correct option is A $\frac{5}{9}$

Given: $2$ blue, $4$ yellow, $3$ red. Total number of balls in the bag $=9$

To find the probability of getting a ball at random which is not yellow

The probability of getting a ball at random which is not a yellow $=$ probability of getting a blue ball or probability of getting a red ball

$=\frac{2}{9}+\frac{3}{9}=\frac{5}{9}$
