Practice problem
Casework and Law of Total Probability
In a certain state: % of people like dogs (dog-lovers), % like cats (cat-lovers), and % do not like either (haters). When these people were asked if they liked rabbits, % of dog-lovers said no, % of cat-lovers said no, and % of the haters said no. What is the probability that a random citizen in the state does not like rabbits?
