Yeah, so first of all you didn't use this inside your function. So, all the first arguments to apply won't have any effect on the result.
Results:
8 + 9 will return 17
8.8 + 8 will return 16.5
will throw an error as the second argument should be an array but you passed a value 2.
If it had been an array sum.apply([8.8,8],[2]); then the result would have been NaN because it will evaluate 2 + undefined.
I hope this answers your question.
