* I have found out that all the different possible answers are between -4 and 11 including 11 and -4. It is not possible to get any answers over 11 and below -4.
I recorded all of this data in a table.
* I have found out that if all 3 dice are the same the total will become the value of one of the die ( Eg. 1+1=2-1=1 ).
* this would be the same conclusion as above if any 2 of the die were the same. (E.g. 2+1=3-1=2)
* I know there is a 50/50 chance of the answer being odd or even because;
odd + odd - odd = odd
even + even - even = even
odd + even - odd = even
odd + odd - even = even
even + even - odd = odd
odd + even - even = odd These are all the possible ways of adding the dice.
Thank you for reading my solution i hope all is correct.
