What is a Venn-diagram?
'A Venn diagram uses overlapping circles or other shapes to illustrate the logical relationships between two or more sets of items.'
According to the given problem,
In a Venn-diagram, the number of people in the orange circle owns cats and those in the blue circle owns dogs.
Now, the number of people in the over-lapping area owns both cats and dogs.
Therefore,
11 people own just cats.
6 people own cats as well as dogs.
Total number of cat-owners = ( 11 + 6 )
= 17
15 people own just dogs
6 people own dogs and cats.
Total number of dog-owners = (15 + 6)
= 21
Hence, we can conclude, the number of cat owners being 17 and the number of dog-owners being 21.
