If `A` and `B` are two events such that `P(AnnB)=0.3` and `P(A'nnB')=0.6`, then the value of `P(AnnB' or A'nnB)` is equal to

A

`0.9`

B

`0.7`

C

`0.3`

D

`0.1`

Text Solution

Verified by Experts

The correct Answer is:
D
`(d)` `P(A'nnB')=0.6`
`impliesP(AuuB)'=0.6`
`impliesP(AuuB)=0.4`
`:. P(AnnB' or A'nnB)`
`=P(AnnB')+P(A'nnB)`
`=P(AuuB)-P(AnnB)=0.4-0.3=0.1`
