Question

A number is selected at random from the numbers : 5, 8, 10, 12, 14, 15, 16, 18, 20, 22, 24, 24, 25, 25, 27, 30, 30, 36, 37, 37, 39, 40, 40, 46. Find the probability that the selected number is a prime number.

Answer 1

Answer:p(A)=1/8

Step-by-step explanation:

S= {5,8,10,12,14,15,16,18,20,22,24,24,25,25,27,30,30,36,37,37,39,40,40,46}

n(S)=24

let

Event A:selected no. is a prime no.

A={5,37,37}

N(A)=3

p(A)=n(A)/n(S)

p(A)=3/24

p(A)=1/8
