Mark the correct alternative in each of the following:

If and then

P(B) = , P = , P(A⋃B) = → (Given)

Now as we know,

P(A⋂B) = P(B) 1/2

P(A⋂B)

→ (1)

Now, according to the addition theorem of probability,

P(A⋃B) = P(A) + P(B) – P(A⋂B)

→ (2)

Now according to the image:

P = P(B) – P(A⋂B)

→ (3)

Also, P( = 1 – P(A)

→ (4)

Now,
