Answer

Explanation:

Step1: Recall the concept of relative - frequency

The relative - frequency of owning a bird is the sum of the relative - frequencies of owning a bird and owning fish and owning a bird and not owning fish.

Step2: Calculate the relative - frequency of owning a bird

The relative - frequency of owning a bird and owning fish is 0.04, and the relative - frequency of owning a bird and not owning fish is 0.02. The relative - frequency of owning a bird is (0.04 + 0.02=0.06).

Step3: Convert relative - frequency to percentage

To convert a relative - frequency to a percentage, multiply by 100. (0.06\times100 = 6%)

Answer:

A. 6%
