If the c.d.f (cumulative distribution function) is given by `F(x)=(x-25)/(10)`, then `P(27 le x le 33)=` . . .

A

`(3)/(5)`

B

`(3)/(10)`

C

`(1)/(5)`

D

`(1)/(10)`

Text Solution

Verified by Experts

The correct Answer is:
A
We have,
c.d.f. as `F(x)=(x-25)/(10)`
`thereforeP(27 le x le 33)=F(33)-F(27)`
`=((33-25)/(10))-((27-25)/(10))`
`=(8)/(10)-(2)/(10)=(6)/(10)=(3)/(5)`
