You are going to have a party and wonder how many people your class are vegans (according to the definition: do not eat meat, fish, eggs or milk products). You send out a survey and ask if they eat A. meat or fish, B. eggs and C. dairy products. You received 60 replies from a total of 60 students. The result shows that • 8 people do not eat eggs and dairy products • 12 people do not eat meat, fish and eggs • 7 people do not eat meat, fish and dairy products • 26 people do not eat fish and meat • 26 people do not eat eggs • 17 people do not eat dairy products. Unfortunately, you do not have a record of how many are neither eating eggs, dairy products, fish or meat. Determine how many people in your class are vegans.
