Question

An integer is chosen at random from the first 200 positive integers. Find the probability that the integer is divisible by 11.

Answer 1

The number of positive integers between 1 and 200 that are divisible by 11 is $\frac{200}{11}=18.18$ (approx.)

So Number of integers in the first 200 positive integers that are divisible by $11=18$.

So the probability =$\frac{18}{200}=0.09$
