Question

A survey was given to 259 people asking where the people like dogs and or cats 186 people said they like dogs 105 people say they like cats 58 said they don't like dogs or cats how many said they like both

Answer 1

90

Explanation:

There are several ways you can go at this, but the basic idea is that "likes dogs" includes "likes both", as does "likes cats."

That means ...

(likes dogs) + (likes cats) + (likes neither)

= (likes dogs only + likes both) + (likes cats only + likes both) + (likes neither)

= [likes dogs only +likes cats only +likes both +likes neither] + (likes both)

= [total] + (likes both)

In numbers, ...

186 + 105 + 58 = 259 + (likes both)

90 = likes both . . . . . . subtract 259
