How many of these people had only a dog_____; How many of these people did not have a cat _____; How many of these people had neither a dog nor a cat____; How many of these people had a cat or a dog ___?

dog only = 51 - 29 = 38
cat only = 48 - 29 = 19
both = 29
none = 150 - 38 - 19 - 29 = 64

not cat = 140 - 48 = 102

cat or dog = 38 + 29 + 19 = 86

hope it helps
