no. of patron have dogs = 14
no. of patron have cats = 10
no. of patron have fish = 5
no. of patron have dogs and cats = 4
no. of patron have dogs and fish = 3
no. of patron have cats and fish = 1
no. of patron have all three pets = 0
no. of patron have only dogs = 7
no. of patron have only cats = 5
no. of patron have only dogs = 1
So total no. of patron have pets =7+5+1+4+3+1=21
So no. of patron don't have any pets =26-21=5
5 patrons don't have any these pets
no. of patron have dogs = 14
no. of patron have dogs = 14
no. of patron have dogs = 14
