: A staff member of a local university reported the following: “Out of one senior class of 500 students, 281 are taking English, 196 are taking English and History, 87 are taking History and a foreign language, 143 are taking foreign language and English, and 36 are taking all three.” Later in the week she was fired. Explain why. This question is from textbook survey of math with applications
You can put this solution on YOUR website! It looks like the total of those taking English + History
English + Foreign Language and those taking all three add
up to more than the 281 supposed to be taking English.
I get
E + H 160 + 36
E + FL 107 + 36
Count the 36 taking all three once, so
160 + 107 + 36 = 303
