avg. number of pets per family  =  (total number of pets) / (total number of families)

 

total number of pets   =   0 * 6  +  1 * 3  +  2 * 3  +  3 * 6  +  4 * 1  +  5 * 1   =   36

 

total number of families   =   6 + 3 + 3 + 6 + 1 + 1   =   20

 

avg. number of pets per family   =   36 / 20   =   9/5   =   1.8
