2) Explanatory variables are synonymical terms for independent variables.
In short when those variables are really not affected by other ones they are also called Explanatory Variables.
It is useful to make a distinction between response variable, and explanatory ones. The first one is affected somehow and it is the response Doris wants to find out.
3) Certainly, the sample or population of this research is absolutely free of prior influence over the final results. Since theoretically, the same research can be done over different samples and find other responses.

Answer:
(a)Dependent
(b)Both
(c)Independent
Step-by-step explanation:
a) When selections are made without replacement, the second(next) outcome is dependent of the first(previous) outcome. Therefore, we subtract one from the draw on the total.
(b)The probability of Event A and Event B is the multiplication of the probability of event A and the probability of event B. Events A and B can either be dependent or independent.
(c)When selections are made with replacement, the next outcome is independent of the previous outcome. Therefore, we say that the two events are independent.
