Thank you for the opportunity to help you with your question!

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.

Please let me know if you need any clarification. I'm always happy to answer your questions.
