Hi, I have the following problem that is solved, but I get lost at one step and cannot find how to do it in the notes. I would really appreciate it if someone could tell me where my teacher gets the result from. The problem says: "Find the matrix of linear mapping T:P_3 → P_3 defined by...

Hi, I have a problem that is already solved... I thought 3 of the 4 functions were probability generating functions, but I got one wrong and don't know why. The solution says g(s)=1+s-s^2 is not a probability generating function. However, g(1)=1 and I think g(s) converges to 1 for |s|<1...
