In what mode do you use Maple?

As I experienced, it works in Document Mode and it doesn't work in Worksheet Mode. There are several grayed characters on the palettes in Worksheet Mode.

 ExpectedValue and StandardDeviation etc. commands in Statistics package are working in this case (with std=10 in the formula above):

ExpectedValue(R);

  0.8331547059

Mean(R);

0.8331547059

StandardDeviation(R);:

8.666532223

In my language there are different words for the two meanings of distribution (probability and funtional), so it is not confusing...

Yes, I also realized, that the Statistics package doesn't work very good in this case.

 As I remember, I just copied the library files in a directory, and I set the path in the maple.ini file, and it works simply without using with.

There is a ReadMe.htm in the downloaded archive (UserLib6789.zip), where you can find the four steps of the library installation, see the part starts with 'In the simplest case, the Library installation can be made in four stages, namely ...'.

This can be done directly with the difff command  in the free Aladjev library:

y := a(t) + b(t)*sin(a(t)+b(t));

difff(y,a(t));
1 + b(t) cos(a(t) + b(t))

difff(f(a(t),b(t)),a(t));

D[1](f)(a(t), b(t))

I have found the following publication on this topic. The authors implemented theirs algorithm in Maple.

As I remember one can embed the display commands.
So you can try something like this, (I hope it works, I can not try it now.) 
...

L[1,1]:=display(p1,p2):
...

display(L);
