1.  An amateur drama group has 15 volunteers for backstage work and 11 for the box office. If 6 volunteers are willing to work either backstage or in the box office, use a venn diagram to determine how many volunteers there are altogether?

2.  Everyone in a doctor’s office is suffering from either Only Child Syndrome (OCS) or a broken funny bone. 13 people raised their hand when asked how many people are suffering from OCS.  8 people raised their hand when asked how many people had a broken funny bone. The nurse noted that 5 people had raised their hands twice.  If there are a total of 23 people in the office, how many are staff? (Assume everyone in the office is either a patient or a staff member.)

3.  There are 115 students enrolled in MDM4U, 93 students enrolled in MHF4U, and 8 of those students are taking both. Illustrate this situation with a Venn diagram and determine the number of students taking at least one of these online math courses.
