Probabily and Statistics : Discrete Random Variable, Probability Mass Function and Cumulative Distribution Function
Not what you're looking for?
A4. A4. Let X be a discrete random variable with range RX = {1, 2, ...}.
(a) Show that
.....
(b) Suppose that X has probability mass function (pmf)
....
(i) Find the cumulative distribution function (cdf) of X.
(ii) Use (a) to find E(X).
IMPORTANT: Could you please add at the end of the question a list of formulae under relevant headings of other distributions I ask for. For example if I ask for binomial forumulae give all the formulae that would be required if the question was exactly the same except about the binomial distribution.
I only want the formulae, not the question re answered.
QA4:
Additional distribution:
Continuous Random variables given instead (also formulae to find Cov(X, Y), exponential function.
