All of the students at a college are majoring in psychology,
business, or both. 73% of the students are psychology
majors, & 62% are business majors.
If there are 200 students, how many of them are majoring in
both psychology & business?
Answer Posted / dr eugene
This is an ambiguous question to which there is no unique solution. It could be that 100% of the 124 business students are also majoring in psychology, in which case the answer is 124. 70 is also a valid answer, for the reasons other people have discuseed, and any number in between.
BAD QUESTION.
