MCQ

Choose the correct answer from the given four options:
Someone is asked to take a number from 1 to 100. The probability that it is a prime is:

A
$\frac{1}{5}$
B
$\frac{6}{25}$
✓
$\frac{1}{4}$
D
$\frac{13}{50}$

✓

Answer

Correct option: C.

$\frac{1}{4}$

Total Number of outcomes = 100
So, the prime number between 1 to 100 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 56, 61, 67, 71, 73, 79, 83, 89, and 97.
$\therefore$ Total number of possible outcomes = 25
$\therefore\ \ \text{Reqired probability}=\frac{25}{100}=\frac{1}{4}$
