MCQ
Probability of getting a number between 1 and 100, which is divisible by 1 and itself only, is
  • A
    $\frac{1}{4}$
  • B
    $\frac{25}{99}$
  • ✓
    $\frac{25}{98}$
  • D
    None of these
✓

Answer

Correct option: C.
$\frac{25}{98}$
(C)
Between 1 and 100 , there are 25 prime numbers.
$\begin{array}{l}\therefore \quad n ( S )=98 \text { and } n ( A )=25 \\ \therefore \quad P ( A )=\frac{25}{98}\end{array}$
