a. What fraction of employers offer only a POS plan?
d. What fraction of employers offer their employees a choice of health plans?
I was able to figure out b & c. So if you can help me with a & d that will be great.
------------------
Procedure:
Draw three intersecting circles; label them HMO, Pos, and Trad
Since 5% offer all three, put a 5 in the intersection of the three circles.
Since 10% offer a Pos and a Trad, put a 5 in the part of Pos/Trad that is
not in Pos/Trad/Hmo
Since HMO/Trad has 10%, put a 5 in the part of HMO/Trad that is not in
Pos/Trad/Hmo
Since P = 25%, put a 15 in the area of Pos that is not in an intersection.
Continue till you have satisfied each of the stated requirements.

Then answer a,b,c,d based on your figures.
