A composite number is selected at random from the first 30 natural numbers and it is divided by 5. The probability that there will be remainder is `14//19` b. `5//19` c. `5//6` d. `7//15`

A

`14//19`

B

`5//19`

C

`5//6`

D

`7//15`

Text Solution

Verified by Experts

The correct Answer is:
A
The number of composite numbers in 1 to 30 is n(S) = 19.
The number of composite numbers when divided by 5 leaves a remainder is n(E) = 14. Therefore, the required probability is `14//19`.
