1. At least one paper = Total people - Non-reader
= 100-20=80.
2. P(M)=70,P(E)=40,MuE= 80 (from question#1),
Hence, MuE= P(M)+ P(E)-Both Newspaper reader(Common)
80=70+40-Both newspaper reader(Common)
Both newspaper reader(Common)=110-80=30.
3.who reads only Morning=70-30 (from question#2)=40.
who reads only Morning=40-30 (from question#2)=10.
Total of who read only one paper (M or E)= 40+10=50
