Draw 3 overlapping circles, D, C and SF.
Way in the middle where all three overlap, put 21
Where only D and C overlap, put 59
Where D has no overlap with others pu 196
now you have to work from the inside out
to figure out how many like each 2 or each 1 exclusively
For example those liking only D and C
59-21 = 38
D and SF = 37-21 =16
C and SF = 32-21 = 11
those liking D alone = 196 - 38-21-16 =
those liking C alone = 153-38-21-11 =
those liking SF alone = 88-16-11-21 =
NOW do the problem
none = 350 - 121-38-21-16-83-11-40 = 20
121+83+40 = 244
Check my arithmetic!!!
