Question

Let us consider the numbers 1,2 ,3, 4,5 .Find the probability of getting a prime number .​

Answer 1

sol

S = { 1, 2, 3, 4, 5 }

n(s) = 5

Let A be the event of getting prime number

A = {1, 3, 5} n(A) = 3

probability of A = n(A)/n(S) = 3/5

the probability of getting a prime number is 3/5
