Suppose the total sample space (area in the rectangle, denoted as S) is all the students on MSU campus. Let A denote all engineering students. Let B denote all freshmen. Let C denote all Seniors.
a) Draw the Venn diagram that represents the relationship of S, A, B, and C. Shade the area that represents non-engineering freshmen
b) Reproduce the Venn diagram and shade the area that represents Engineering Freshmen and Engineering seniors
