  7. probability - Expectation - product of expectations is expectation of ...

    May 1, 2019 · I thought the expectation of a product is the product of expectations, but this is not what has happened. Someone we have managed to get an extra expectation out of the front. Any ideas? …

  8. statistics - What is the expectation of $ X^2$ where $ X$ is ...

    I know that if X X were distributed as a standard normal, then X2 X 2 would be distributed as chi-squared, and hence have expectation 1 1, but I'm not sure about for a general normal.

  9. Expected value of $2^X$ - Mathematics Stack Exchange

    Mar 23, 2016 · If I have to calculate $\\mathrm{E}(2^X)$, is it then just $(2^{x_1} \\cdot p_1) + (2^{x_2} \\cdot p_2) + (2^{x_3} \\cdot p_3)$ etc.? Like $\\mathrm{E}(X)$ is just ...
