Formulas in New Quizzes

[glaviolette]

I am just learning to use  "Formula" questions in New Quizzes.  I would really like to create a random set of 25 numbers 5-10.  I want the students to then completely a frequency table based off of the numbers or at least determine the frequency table of one value as a first question.  How can I do this?  I don't know what to enter as the formula so that the count of, let's say 7s, will be taken.  Thank you in advance!
