Make a table of outcomes, S=sum:
(Sorry, I have not found a way to line up the columns).
S -1 -5 -6
-5 -6 -10 -11
4 3 -1 -2
8 7 3 2
Out of the 9 outcomes, how many are negative? Hence deduce the probability.
if you have two spinners,the first spinnerr has three sections: -1,-5,-6.the second spinner also has three sections:-5,4,8.if you spin both spinners and ADD the two numbers,what is the probability that the sum will be negative?
