It's a Venn diagram problem. 50 patrons, 16 of them like lattes, 12 of them like espressos, and 8 of them like both coffee drinks. How many patrons don't like either of the coffee drinks.
A) 32
B) 22
C) 14
D) 30
Since I can't draw the Venn diagram, I will solve it mathematically. Let n be the number of drinkers:
n( lattes) = 16 n(espresso) = 12 n(elates AND espresso) = 8 Let's find the number of those who drink either latte or espresso) n(Lattes OR espresso) = n(lattes) + n(espresso) - n(lattes AND espresso) n(Lattes OR espresso) = 16 + 12 - 8 = 20 Then 20 likes either lattes or espresso + 8 likes both = 28 like coffee The total is 50, out of them 28 like coffee, then those who don't like coffee are: 50-28 = 22 (answer B)
