#### 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 : Option 1) 1/4 Option 2) 5/17 Option 3) 8/17 Option 4) 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.
