Since there are five short-answer questions and she randomly selects one for a quiz, this can be written as 1/5 because there are 5 choices, but only one can be selected.
Therefore, the probability that she will select question #3 is a 1/5 or 0.2 chance.
To fill in the first column = Every day is 7 dollars, which you have already answered. The second one would be = day 0 = 30 dollars. And then it would be 4$ for days 1 through 10. Hope this helps!
