What you can do is:
- you sum all the number inside of the array using .sum
- then you change the total from being an integer to a float number using .to_f
- then you divide that by the total number of elements inside the array using .size
- then you change that number from an integer to a float using the .to_f
It looks like like this:
arr = [0,4,8,2,5,0,2,6]
