Question

A bag contains 10 blue balls and 12 yellow balls. What is the probability of getting a yellow ball ?

• A. $\frac{1}{11}$
• B. $\frac{5}{11}$
• C. $\frac{5}{13}$
• D. $\frac{6}{11}$

Answer 1

The correct option is D

$\frac{6}{11}$

Total number of balls in the first bag=10+12=22

Number of yellow balls=12

The probability of getting yellow ball =$\frac{12}{22}$$=\frac{6}{11}$
