Question

From $101$ to $1000$ natural numbers a number is taken at random. The probability that the numberis divisible by $17$ is

• A. $\frac{58}{900}$
• B. $\frac{58}{100}$
• C. $\frac{53}{900}$
• D. $\frac{53}{1000}$

Answer 1

The correct option is C $\frac{53}{900}$

Multiples of $17$ between $1000$ and $101=986/17-85/17=53$
$P=53/(1000-100)=53/900$
