Bit confused, thought it was asking me to write out the possible combinations, i.e 3,4,5,6 and their respective probabilities? If it wanted this what would it ask, and what exactly does range mean?

Thanks

That is a rather deviously worded question; not surprised you had problems.

If it wanted, 3,4,5,6 it would have said the sum of the three balls.

Here the range of the three balls, is the highest value minus the lowest value.
E.g. (1,1,1), has a range of 1-1=0
(1,1,2) has a 2-1 = 1

Edit: Too slow again!

look at some similar examples here

thanks both of you

so range - > look at possible samples and find ranges of each of them i,e (1,2,2) (1,1,1) etc
sum -> do what I did i.e find probabilities off each possible total sum
