For problems 15 through 20, create Venn Diagrams to help you solve the problems. These are not easy diagrams, take your time and think through this carefully.
Hints on 15 (highlight the following paragraph with your mouse to see them, they are in the form of questions you'll need to answer):
<start highlighting here> You aren't meant to find out how many students are in the individual courses. How many students are you supposed to have counted? How many wound up being counted? What does the overage mean? How many times too many was a student counted if he was in all three classes?<end highlighting here>
15. 500 students are enrolled in at least two of these three classes: Math, English, and History. 170 are enrolled in both Math and English, 150 are enrolled in both History and English, and 300 are enrolled in Math and History. How many of the 500 students are enrolled in all three?

Make a Venn Diagram from the following information to answer questions 17 through 20:
25 students played soccer
4 boys played soccer and baseball
3 girls played soccer and baseball
10 boys played baseball
4 girls played baseball
9 students played tennis
3 boys played soccer and tennis
3 girls played soccer and tennis
3 boys played baseball and tennis
1 girl played baseball and tennis
1 boy played all three sports
1 girl played all three sports
Hints on the diagram (highlight the following paragraph with your mouse to see them):
<start highlighting here> Notice that the counts don't make sense as they are, because they're all inclusive. The soccer count includes every who plays soccer, even the students in the soccer and baseball, soccer and tennis, and the all three sport counts. The count for soccer and baseball includes the students who play all three sports. So you'll need to correct from the inside outward...first subtract the boy and girl who play all three sports from all the other counts, then subtract the dual-sport counts from the single sport counts.
Put another way, this is like the gecko problem--the entire soccer circle including the soccer and baseball students and the soccer and tennis students and the students who play soccer and baseball and tennis, will add up to 25.<end highlighting here>
