Question

A number is chosen at random from 1 to 25. Find the probability of selecting a composite number.

Answer 1

Answer:

S={1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,

19,20,21,22,23,24,25}

n(S)=25

(A):composite numbers

S(A)={4,6,8,9,10,12,14,15,16,18,20,21,22,24,

25}

n(A)=15

probability of getting composite numbers=n(A)/n(S)

=15/25

=3/5

= 0.6

Step-by-step explanation:

Answer 2

total composite no. between 1 &25= 15

so, 15/25= 3/5
