## dice probability game with graph of results

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)
x=1:1000
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.

You probably also want

```plot(x,Numberof6s)
```

rather than

```plot(Numberof6s,x)
```
