Answer:

80.

Step-by-step explanation:

Let $C$ be the set of people who like cats and $D$ the set of people who like dogs. Under the cardinality theorem you have

n(CUD) = n(C) + n(D) - n(CnD)[/tex], isolating the $(C$ ∩ $(D$ , you have n $(C$ ∩ $(D$ = n(C) + n(D) - $(C$ ∪ $.As a total of 339 individuals, and 88 are those who do not like cats or dogs, then 251 of them are those who like cats or dogs. Then, n[tex](C$ ∩ $(D$ $= 190 +141 -251 = 80$
