Question

In a survey , it was found that 40% people use petrol , 35% use diesel and remaining CNG for their vehicles. Find the probability that the person chosen uses CNG. Which is more appropriate for use?

Answer 1

Percentage usage $\left(CNG\right)=100-40-35=25$

So, probability $=\frac{25}{100}=\frac{1}{4}$
