A survey was given to 309 people asking whether people like dogs and/or cats. 121 said they like dogs 180 said they like cats 60 said they don't like cats or dogs . How many said they liked both cats and dogs?

121 people liked dogs, 180 said they liked cats. Do 309-60 which is 249 Because we don’t need the number of ppl who dont like cats or dogs. Then do 180+121 which is 301. 306-301 is 5. That means 5 people said they liked both cats and dogs
