Hello I tried to plot this but it's show me "Vectors must be the same length.

Error in (line 17)

plot(difference,probability,'b--'"

would you please help me to fix the problem?

thanks in advance.

difference=[];
probability=[];
for diff=-5:1:5
    sum=0;
    for g=1:6
        for r=1:6
            
            if(g-r==diff)
                sum=sum+(1/36);
            end
        end
    end
    differnce=[difference diff];
    probability=[probability sum];
end
figure
plot(difference,probability,'b--')
xlabel('D');
ylabel('P');
axis([-5 5 0 .2]);
