Mark the correct alternative in each of the following:

If and then is equal to


→ (Given)


To find →


→ (1)


Let’s find the required values first and then we can put them into equation (1) to find the answer.


P(A) = 1 – P()


P() = 1 – P(A)




P(B) = 1 – P()


= 1 – P(B)




Also, according to the addition theorem of probability,


P(A⋃B) = P(A) + P(B) – P(A⋂B)






Also,



= 1 – P(A⋃B)




Now let’s put all the values in Equation (1)


P=
