Can you tell me if I have gotten this correct? If not can you tell me what direction I should going to?

An economics quiz contains seven multiple-choice questions. Let x represent the number of questions a student answers correctly.

Total questions = 7

Let x be the number of questions a student answers correctly

a. Is x a continuous or discrete random variable?

Ans: Hence X is finite value and X is discrete variable.

b. What are the possible values of x?

Ans: x=0, 1, 2, 3, 4, 5, 6, 7

(Use a comma to separate answers as needed. Use ascending order.)

You have the answers correct except for the capitalizations of x/X.

For example:

>> Is x a continuous or discrete random variable?

should be:

Is X a continuous or discrete random variable?

since lowercase x is defined by:
