dice probability game with graph of results

Asked by Brian
on 15 Jun 2013

I have to create a simulation of a player throwing two dice (1:6) then summing the total of the two throws eg 3+4 gives 7. I have to count the number that gives a total of 6. I did that part fine, but I need a graph of the number of throws vs the number of throws which resulted in a 6 with a line showing the theoretical value, which the throws should converge to.

This is what I did:

r  = randi([1 6],1000,1);
d = randi ([1 6],1000,1);
e = r+d
out = e(6)
rangesLowValue = 6;
rangesHighValue = 6;
Numberof6s  = sum(e(:) >= rangesLowValue & e(:)<=rangesHighValue)
plot(Numberof6s,x)  %Don't know what to do here. 

Thanks for any help.

Try the cumsum() function instead of the sum() function, and I think you get what you intended.
