Works here. Probability is new in version 8. Are you using version 8? $Version "8.0 for Mac OS X x86 (64-bit) (October 5, 2011)" Probability[x == 3, Distributed[x, PoissonDistribution[m]]] ((1/6)*m^3)/E^m Bob Hanlon On Mon, Nov 14, 2011 at 7:07 AM, Brentt <brenttnewman at gmail.com> wrote: > Hello, > > If I go to the Probability function documentation, and evaluate a > probability function in the documentation notebook, the probability > function works as would be expected, for example: > > In[0]:= Probability[x == 3, Distributed[x, PoissonDistribution[m]]] >> Out[0]= 1/6 E^-m m^3 >> > > So far so good. > > But strangely, if I open up a new notebook and copy and paste the exact > expression from above into it, I get this > > In[0]:= Probability[x == 3, Distributed[x, PoissonDistribution[m]]] >> Out[0]:= Probability[True, 3 \[Distributed] PoissonDistribution[m]] >> > > What could possibly be happening here?
