5. Which values of x make the following true? x is a factor of 12 AND x is a factor of 28 Solution: x is a factor of 12 AND x is a factor of 28 1,2,3,4,6,121,2,4,7,14,28 what is common in both: 1,2,4 x is a factor of 12 OR x is a factor of 28 Solution: x is a factor of 12 OR x is a factor of 28 1,2,3,4,6,7,12,14,28 these answers with OR means that they show up on at least one of the lists (but could be on BOTH lists)

6. Venn Diagrams

7. Last example: Nick likes girls that are smart OR rich

8. Venn Diagram The following example using sports Running, Swimmer, Biking How many do all 3 sports? How many only do each one? How many run and bike? How many bike and swim? How many run but do not swim? How many don’t do anything? How many kids are there in total?

9. Do the following example Ex. Grade 11 students 380 took Bio 240 took Chem 150 took physics 125 took all 3 100 took none 140 took physics and chem 220 took bio and chem 130 took bio and physics How many took only bio? How many students ?
