Hello. I'm college students and I'm so confused on this equation. This is the equation:
A survey of 77 freshmen business students at a large univversity produced the following results:
25 of the students read Bloomberg Businessweek
19 read The Wall Street Journal
27 do not read Fortune
11 read Bloomberg, but not The Wall Street Journal
11 read The Wall Street Journal and Fortune
13 read Bloomberg and Fortune
9 read all these.
I have to figure out how many students read none of the publications, how many students read only Fortune, and how many students read Bloomberg and The Wall Street Journal, but not Fortune. Here's what I got so far I did the easiest ones first, but from there, I was lost since it's so hard to answer something when you don't have the full information.
So I would like to know how to at least know where to go from there, so that I am able to answer this question with an understanding on problems like this in the future. Any clarification will be appreciated
