Roll the dice (advanced)

Solution

When you first open the page:
- the default value for Number of dices is 3
- the default value for Number of rolls is 1
Number of dices should be between 1 and 9, while the Number of rolls is limited to 10
Show for every roll:
- the sum of all dices
- the average (rounded to maximum two decimal digits) of all dices
- one line with dice images (assets/dice/dice-n.png)
If the sum of all dices on a line is EVEN: show the result inside a div tag with class box-primary
If the sum of all dices on a line is ODD: show the result inside a div tag with class box-warning

Round the average with the functions round() and number_format() to see the difference (in output)
