How can I draw Empirical graph of dice propblem

I'd like to make a code which can make the empirical graph of dice when the dice is only "6"

However, as you can see, the probability is not the same as theory. 

Is there anybody telling me the mistake that I did?  The answer has to be '0.166666666...'

 

plz, help me

rnd(5) creates a float random number in the range 0 .. 5

You ask for the number being > 4 and count the range from 4 to 5 which is 1/5 of the range 0 to 5. Consequently you get a result near 0.2.

 

Use rnd(6) and condition ">5" and you get the result you'd like to see.

Something like this perhaps:

There are other ways as well of course!

I thought that rnd Function is similar to randi in Matlab.

It is not an integer in Mathcad
