Question

The Venn diagram represents the results of a survey that asked participants whether they would want a dog or a cat as a pet.

Answer 1

For this case, from the diagram we can conclude the following results according to the surveys:

 For Dogs:
 Dogs = 24 + 31 = 55
 No dogs = 10
 Total = 65

 For the cats:
 Cats = 10 + 31 = 41
 No cats = 24
 Total = 65
