Joint distribution of sums of exponential random variables
math
This is a problem from Ross’s Stochastic Processes
[1]
. Let
\[ \begin{aligned} S_1 &= X_1\\ S_2 &= X_1 + X_2\\ S_3 &= X_1 + X_2 + X_3 \end{aligned} \]

Probability of even/odd using probability generating functions
math
A probability generating function for a discrete random variable
\(X\)
taking values
\(\{0,1,\ldots\}\)
is defined as
\[ G(z) = E[z^X] = \sum_{j = 0}^\infty z^j P(X = j) \]
