Question 64044: I know I posted this wrong, but I hope some one can help me out with this:
Here is the Questions below:
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
12 girls played at least one of the three sports
Hints on the diagram (highlight the following paragraph with your mouse to see them):
Notice that the counts don't make sense as they are, because they're all inclusive. The soccer count includes everyone 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 two students who play soccer/baseball/tennis. 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.
