(11-15). Two dairy farmers (farmer1 and farmer2) accidentally allowed some of their cows to graze in a pasture containing weeds that would contaminate the milk from their herds. Farmer-1 has 5 cows and estimates that there's a 10% chance of a cow grazing on some of the flavorful weeds. Farmer-2 has 7 cows and estimates that there's a 20% chance of a cow grazing on some of the flavorful weeds.
