Question

Having $10$ years of experience of selling $200$ or more products

• A. $\frac{10}{20}$
• B. $\frac{1}{10}$
• C. $\frac{1}{25}$
• D. $\frac{1}{8}$

Answer 1

The correct option is D $\frac{1}{8}$

Total number of salespersons$=1000$

Number of salespersons who is experienced for 10 years and selling 200 & more than 200 products$=50+75$

$\therefore$ probability $P=\frac{125}{1000}=\frac{1}{8}$

hence, option $D$ is correct.
