Question

A number is selected at random from the first five natural numbers. Find the probability that the number is a prime?​

Answer 1

Answer:

let take Natural number is N

Now N=1,2,3,4,5........(The natural numbers starts from 1 onwards)

the prime numbers are 2,3,5.......

answer =N differenced Prime number

=1,2,3,4,5

From this 2,3,5 is the answer

but probability 2,3 is the answers

Answer 2

First five natural numbers are 1, 2, 3, 4 and 5.

prime numbers in first 5 natural numbers = 2, 3 and 5.

Probability = No. of possible outcomes/Total no. of outcomes.

No. of possibilities for a prime number = 3 (2, 3 and 5)

Total no. of numbers = 5

Probability for a prime number in first 5 natural numbers = 3/5.
