Answer:
0.55% probability that exactly 5 out of the first 13 customers buy a magazine
Step-by-step explanation:
For each customer, there are only two possible outcomes. Either they buy a magazine, or they do not. The probability of a customer buying a magazine is independent of other customers. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
10% of his customers buy a magazine
This means that 
What is the probability that exactly 5 out of the first 13 customers buy a magazine?
This is P(X = 5) when n = 13. So


0.55% probability that exactly 5 out of the first 13 customers buy a magazine

Step-by-step explanation:
The first choice is correct.
in the first function f(x)=3x-2, the smallest value is when x=-1, y=-5, the largest value is when x=0, y=-2, but it doesn't include -2 because there is no = sign.
in the second function, the smallest value of y is when x=0, y=3, the largest value is y=13, but it doesn't include y=13
