i have a question which it is the following:
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, i.e. the relative frequency.
i wrote the following code but it is not working any body got an idea how to solve this question?
function p = sim()
N = 10^3;
s=0;
k=0;
for i=1:1000000
p=randi(6,1,2);
if sum(p)==8
k=k+1;
end
end
end

You didn't define p (which should be k/1000000).
But instead of 1000000, you are told to use N = 10^3 , aren't you ?
And the variable s is superfluous - so you should delete it.
