All right, have you tried drawing this yet?

OpenStudy (anonymous):

total 50 students were interviewed. it looks like you have 3 stories that the students read

OpenStudy (anonymous):

Story 5, 8, 13

OpenStudy (anonymous):

so imagine 3 intersecting circles

OpenStudy (anonymous):

I have tried to draw it several times but my numbers dont add up

OpenStudy (anonymous):

each circle represents one story: A represents Story 5, A represents Story 8,A represents Story 13

We can begin to fill in the intersections. Intersection ABC is the intersection of those who like story #5 and story #8 and story #13. which is 4 students
