High school Combination problem help?
Last year at the independent leaning center, a group of 48 students enrolled in math, french and physics. Some students were more successful than others: 32 passed french, 27 passed physics, and 33 passed math; 26 passed french and math, 26 passed physics and math, and 21 passed french math a physics. How many students passed one or more subjects?
(6 marks for venn diagram, 2 marks for principle)
**i don't need help with the venn diagram**
I don't even think I am on the right track. So far I have been looking at the highest number of people who failed one subject, 21 people for physics, and subtracting it from the total number of students to get 27 people that have passed that. There are 32 people who passed french and 33 who passed math. Would 27 work because that is the lowest amount of people that could pass?
