**DRAW A VENN DIAGRAM FOR pg 218 #5**

I don't understand how to do problem 5 on page 218. When I did 49+35, I got 84, which doesn't make any sense since the survey only interviewed 80 people. I am very lost. Please tell me if I am over thinking the problem.

ReplyDeleteDear Lost,

DeleteMake a "typical" 2-circle Venn diagram with an intersecting region in the center... 80 is the total number surveyed... label the left circle "Take Pictures" and label the right circle "Play Games"... since 35 like to do both, that is the number that goes in the intersecting region... the TOTAL NUMBER that take pictures is 49... 35 are already accounted for in the intersecting region, so the remainder is the number that "Take Pictures" ONLY...

lmk if you are FOUND!

Oh, thanks for this! I was confused, too.
