If A and B are any two events such that P(A)=2 /5 and , then the conditional probability,
where
denotes the complement of A, is equal to :
1/4
5/17
8/17
11/20
As we learnt in-
Demorgans Laws -
If A and B are any two sets then
- wherein
where A1, A2.....An are n events
And,
Conditional Probability -
and
- wherein
where probability of A when B already happened.
Here,
Option 1)
1/4
This option is incorrect.
Option 2)
5/17
This option is correct.
Option 3)
8/17
This option is incorrect.
Option 4)
11/20
This option is incorrect.
