Please clarify: it looks like you are trying to provide a table like this:


\begin{matrix}
X & P(X) \\
0 & 0.07 \\
1 & 0.19 \\
2 & 0.23\\
3 & 0.17 \\
4 & 0.16 \\
5 & 0.14 \\
6 & 0.04
\end{matrix}


I'm not sure what you mean by "P(2 X 5)" - do you mean "probability of 5 occurring twice in a row," or do you mean "probability of 2 occurring then 5," or something else?
