  1. 32 is C

    n(P ∩ Q ∩ R) = n(P) +n(Q) + n(R) - n(P ∩ Q) - n(P ∩ R) - n(Q ∩ R) + n(P ∩ Q ∩ R)

    Hence, newspaper P only is n(P) - n(P ∩ Q) - n(P ∩ R) + n(P ∩ Q ∩ R)

    2. Totally C, 100%. First off, when they mentioned those who bought P, P(P) u automatically judge that a portion of those ppl bought nsp Q, R or both. Then the later, when they mentioned those who bought nsp P and Q, if u studied deeply enough, it is understood that in that crowd, some of them bought P and Q only, P(P∩Q∩R*), and some of them bought P, Q and R, P(P∩Q∩R). You have to take this into account, noticing that they didn't mention the word 'only', which if present implies an intersection with the region R*. Well, enough, u did not exclude any others when they first mentioned those who bought P, but now, u instead exclude R out of the set P∩Q. That is awfully not right as it would mean u r using two logics and they both contradict each other. Standard probability rules states in this case u CANNOT exclude R. You definitely cant say that if a person buys nsp P, Q and R, they are not considered buying P and Q and they would subsequently be excepted from that set. Truly, u see how ur own logic outplayed you. If u decide to continue using ur logic here, it would turn into a case as such if imposed on banking statistics. Every person has three accounts. There will be a loyalty reward for those who have $1000 in the first account and $5000 in their second account. Well enough, you have $1000 in ur first, $5000 in ur second and $500 in ur third. Tell me, will u be excluded from those who have $1000 and $5000 for the accounts respectively.
