Question

What is the probability of the event that a number chosen from 1 to 100 is a prime number?​

Answer 1

Answer:

As per the question,

We know that a prime number is defined as the number which has two factors, one and the number itself.

The prime numbers from 1 to 100 are:

2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.

Therefore, total prime numbers from 1 to 100 = 25

Number of way of choosing prime number = 25C₁ = 25

Number of way of choosing any number = 100C₁ = 100

probability=25/100

Probability= 1/4

Hence, the probability of the event that a number chosen from 1 to 100 is a prime number Probability= 1/4

Answer 2

Answer:

1/4

Step-by-step explanation:

Number of prime number between 1 - 100 =  2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97 = 25 events

Total outcomes from 1 - 100 = 100

Probability = Events / total possible outcomes = 25/100 = 1/4

Hope its clear
