A survey of 100 students at a college finds that 50 take math, 40 take English, and 30 take history. Of these 15 take English and math, 10 take English and history, 10 take math and history, and 5 take all three subjects. (This question relates back to question #17.) For each of the following draw a Venn Diagram and shade the indicated sets and determine the number of students in the set.
Students who take at least one of these classes
Students who take exactly one of these classes
Students who take at least two of these classes
Students who take exactly two of these classes
Students who take at most two of these classes
Students who take English or Math but not both
Students who take Math or History but not English
Students who take all of these classes
