    A survey of 75 people found 45 like rabbits, 32 like hamsters, and 15 like both animals. How many people like neither animal?

    People who like either rabbits or hamsters = Rabbit liners + hamster likes - both likers
    People who like either rabbits or hamsters = 45 + 32 - 15
    People who like either rabbits or hamsters = 62

    People who like neither = 75 - People who like either rabbits or hamsters
    People who like neither = 775 - 62
    People who like neither = 13
