If `A` and `B` are two events such that `P(A)=4/5`, and `P(AnnB)=7/(10)`, then `P(B//A)=`

A

a) `1/10`

B

b) `1/8`

C

c) `7/8`

D

d) `17/20`

Text Solution

Verified by Experts

The correct Answer is:
c) `7/8`
Given,

`P(A)=4/5`, and `P(AnnB)=7/(10)`

`P(B//A)=(P(AnnB))/(P(A))`

`P(B//A)=(7/10)/(4/5)`

`P(B//A)=(7/8)`

Hence, correct option is c)
