Of 500 newly admitted college students, 220 are enrolled in Intermediate Algebra, 320are enrolled in English 1 and 125 are enrolled in both.Part A: Complete the following Venn Diagram with the number of elements in eachsectionA = Intermediate AlgebraB = English 1B320220APart B: How many elements are in the subset (ANB)Part C: How many college students are in ASPart D: How many college students are in the subset -(AUB)

Answer 1

From the diagram we can see that 95 people are enrolled only in Intermediate Algebra, 195 are enrolled only in English 1 and 290 are enrolled in (English 1 ∪ Intermediate Algebra).

Given this, we can say that 210 students are not enrolled in either Intermediate Algebra or English 1, that is to say, the set

-(Intermediate Algebra ∪ English 1) has 210 elements.
