When you want to find zeros of rational expression you need to find at which points numerator is equal to zero. In this case, we have the product of three expressions.

A product is equal to zero whenever one of the factors is equal to zero.
That means that zeros of our functions are:
1)

2)


3)


The final answer is a. Function has zeros at (0, 1, -11).
The key word here is "or". If it's an OR question, you add the probabilities together. If it says "and", you multiply them together
As it is an OR question though, you add them.
So:
15 + 5 = 20%
