In eight thows of a die `1 or 3` is considered a success. Then, the standard deviation of success, is

A

`(16)/(9)`

B

`(8)/(3)`

C

`(4)/(3)`

D

`(2)/(3)`

Text Solution

Verified by Experts

The correct Answer is:
C

We have ,n=8 and p`=2/6 =1/3`
`therefore ` SD `=sqrt(npq)=sqrt(8xx(1)/(3)xx(2)/(3))=4/3`
