P(A)=People subscribing  daily morning edition

P(B)=People subscribing  the Sunday editions

P(AUB)=P(A)+P(B)-P(A Both B)  ...........(1)

Given that P(AUB)=900; P(A)=700;and P(A both B)=400

From equation(1), we have

900=700+P(B)-400 ; P(B)=600

Thus People subscribing the sunday edition P(B) is 600.

Tutor went the extra mile to help me with this essay. Citations were a bit shaky but I appreciated how well he handled APA styles and how ok he was to change them even though I didnt specify. Got a B+ which is believable and acceptable.
