*A marks list is available for a class of ten students. Design a program to output the mean mark for the class.*

`<?`

` // ten students all have marks`

` // for this solution, the marks are going to be from 0 (all wrong) to 10 (all correct)`

` $student_marks = array(3, 7, 2, 5, 10, 7, 9, 0, 2, 3);`

` `

` // add up all the values in the arry`

` // then divide by the number of values in the array`

` // this solution would work for any number of students`

` $mean_mark = array_sum($student_marks) / count($student_marks);`

` `

` // output the result`

` echo 'Mean mark: ' . $mean_mark;`

`?>`

Which produces:

Mean mark: 4.8
