Answer 2

If P(A) = 2/3 then P(Ā) = 1/3

Correct question : If P(A) = 2/3 then P(Ā) = ?

Given :

P(A) = 2/3

To find :

The value of P(Ā)

Solution :

Step 1 of 2 :

Write down the given probability

Here it is given that for an event A

P(A) = 2/3

Step 2 of 2 :

Find the value of P(Ā)

We know that for any event A

P(A) + P(Ā) = 1

⇒ P(Ā) = 1 - P(A)

⇒ P(Ā) = 1 - 2/3

⇒ P(Ā) = 1/3

Thus we get P(Ā) = 1/3
