calculating probability in Matlab

i have this question:

create a MATLAB function that approximates the probability in the following experiment with simulations!Two fair dice are thrown. Find the probability that the sum of the numbers obtained is 8.

The number of simulation should be N = 10^3. The variable p should store the approximation.

function p = sim()
    N = 10^3;

    p =     ;
end

does any body have an idea how to continue from here?

Answer 1

[Torsten]

p = sim()

p = 0.1330

5/36

ans = 0.1389

function p = sim()
N = 10^3;
k=0;
for i=1:N
    p=randi(6,1,2);
    if sum(p)==8
        k=k+1;          
    end
end
p = k/N;
end
