Q37 of 249 Page 31

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,
