The definition of a function is a relation where every input (x value) is paired with exactly one output (y-value).
A. Not a function, because you have (300, 9) and (300,7). The x-value 300 is paired with two different y-values, 9 and 7.
B. Not a function. (260, 4) and (260, 2)

Answer:
A. 7%
Step-by-step explanation:
We build the Venn's diagram of these probabilities.
I am going to say that:
A is the probability that a resident owns a car.
B is the probability that a resident owns a truck.
We have that:

In which a is the probability that a resident has a car but not a truck and
is the probability that a resident has both a car and a truck.
By the same logic, we have that:

4% of residents own both a car and a truck.
This means that 
56% of residents own a car
This means that
. So



What is the conditional probability that a person who owns a car also owns a truck?

So the correct answer is:
A. 7%
