Question

What is the probability of the
event that a number chosen from to 100 is a Prime Number.​

Answer 1

$\huge\underline{\underline{\orange{\mathcal{Answer}}}}$

There are 25 prime numbers between 1 and 100

2,3,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61,67,71,73,79,83,89,97

So, probability of the event that a number chosen from 1 to 100 is a prime number = $\frac{25}{100} = \frac{1}{4}$
