a dozen oranges give me a gallon of juice?
the trees have the same age and are all of the same variety, I know that 12 oranges give me a gallon of juice, well sometimes I get the gallon with 11 oranges and the other day it took me 13 oranges.
I sold 360 oranges to these boy-scouts so they would make money selling juice, I talked to their Rover and he said the kids got to sell 36 gallons. Now I wonder, what is the probability they diluted with water?
