do anyone have example how this is done

Define the array that is the result of the exam seven students who took the subject of Web services and have won 77, 98, 56, 87, 64, 55, 82 points. Print all of the results, the minimum and maximum number of points, compute the average winning score per student.

I am confused at min and max number of points, that is 100 right? so I need to count avarage number for example of 77 in percents or what, from 0 to 100, what avarage number, 77 is only number that student won

or I might need to set min and max from those numbers, but what next, its not avarage of all students together, but for every single student, student that won 77 points what is avarage for that, its 77
