3 overlapping circles (R and B and S), 8 areas (RO, BO, SO, RBO, RSO, BSO, RBS, NRBS)
circle R for raspberries, R only or RO just raspberries
circle B for blueberries, B only or BO just blueberries
circle S for strawberries S only or SO just for strawberries
RB both raspberries and blueberries, RBO just raspberries and blueberries
RS both raspberries and strawberries, RSO just raspberries and strawberries
BS both blueberries and strawberries, BSO just blueberries and strawberries
RBS rasberries, blueberries, and strawberries
NRBS is none of the 3 types
R = RO + RBO + RSO + RBS = 75
B = BO + RBO + BSO + RBS = 40
S = SO + RSO + BSO + RBS = 27
RBS = 4 (all 3 types)
RB = RBO + RBS = 11 = RBO + 4 --> RBO = 7 (not strawberries)
RS = RSO + RBS = 10 = RSO + 4 --> RSO = 6 (not blueberries)
BS = BSO + RBS = 14 = BSO + 4 --> BSO = 10 (not raspberries)
R = RO + RBO + RSO + RBS = 75 = RO + 7 + 6 + 4 = RO + 17 --> RO = 58 (raspberries only)
B = BO + RBO + BSO + RBS = 40 = BO + 7 + 10 + 4 = BO + 21 --> BO = 19 (blueberries only)
S = SO + RSO + BSO + RBS = 27 = SO + 6 + 10 + 4 = SO + 20 --> SO = 7 (strawberries only)
8 areas --> RO = 58, BO = 19, SO = 7, RBO = 7, RSO = 6, BSO = 10, RBS = 4, NRBS = 9
total fruit tree growers surveyed is sum of all 8 areas or 58 + 19 + 7 + 7 + 6 + 10 + 4 + 9 = 111 + 9 = 120
none of the 3 types or only blueberries --> 9 + 19 = 28
