Answer:
Option B: 600 is the correct answer.
Explanation:
In order to solve this question, we will first find the probability or ratio of people out of 200 who will love to have pig as a pet
We know that
Sample size = n(S) = 200
Let A be the event that people will pick pig as pet
Number of people who pick pig = n(A) = 12
Thus the probability is:

0.06 is the probability for the sample of 200. To find it for the whole population we will simply multiply the probability with population size.
So,

Hence,
Option B: 600 is the correct answer.
