Answer:
1/6
Explanation:
In the problem, a survey was conducted on 'x' number of people by the producer of two different products (P and Q). Therefore:
x/3 people bought P but not Q
x/2 people bought two products.
If 'y' represents the number of people that didn't buy any of the two products. We can say that:
x/3 + y = x/2
y = x/2 - x/3 = (3x-2x)/6 = x/6
Thus, the fraction is 1/6.
