Anew school randomly assigns a five character student code to every prospective student. the school uses the characters 1,2,3,4,5,w, x,y, and z. if bon of the student codes contain a repeated character ehat is the total nber of codes that can. be randomly assigned

I'm pretty sure you multiply the amount of characters they use, which is 9, by the number of students in the school.

For example, if there were 589 students, you'd multiply 589*9 which is 5301. So for a school with 589 students there'd be 5301 codes they could use before they'd either reuse codes or get a new set of characters.

I hope that helps!

Where are the following equations?
