Hi

This Carl Code evaluates fine

MySumP:= (j::integer)->
    seq(combinat:-numbcomb((j+10),(i+10))*p^(j+i)*(1-p)^(j+i), i= 0..0);
:[MySumP(10)]


[184756*p^10*(1 - p)^10]

But what I would like is whats inside the numbcomb argument to be displayed.

i tried

MySumP:= (j::integer)->
    seq(combinat:-numbcomb(``(j+10),``(i+10))*p^(j+i)*(1-p)^(j+i), i= 0..0)
:

[MySumP(10)]

What i would like displayed: numbbomb(20,10)*p^10*(1-p)^10 or (better) C(20,10)*p^10*(1-p)^10
Please Wait...
