Returning to Example 3.2.1, now using the notation of Definition 3.2.1, we found that the pmf for X at 1 is given by. p(1) = P(X = 1) = P({ht, th}) = 0.5. Similarly, we find the pmf for X at the other possible values of the random variable: p(0) = P(X = 0) = P({tt}) = 0.25 p(2) = P(X = …

PMF The PMF of a random variable X X is a function associating the possible values of X X and their associated probabilities; for example pX(xi) = P (X = xi) p X ( x i) …

Calculating the variance using the Probability Mass Function (PMF)

https://math.stackexchange.com/questions/4159911/calculating-the-variance-using-the-probability-mass-function-pmf

You could calculate the variance by obtaining the explicit 'density' for X Y first. You do this by, for every value z that X Y may take, summing the joint probabilities of all …

Given a pmf, how is it possible to calculate the cdf?

https://stats.stackexchange.com/questions/433028/given-a-pmf-how-is-it-possible-to-calculate-the-cdf

You can compute the CDF using delta-functions. Express the PMF as follows, p ( x) = ( 0.4) δ ( x − 1) + ( 0.3) δ ( x − 2) + ( 0.2) δ ( x − 3) + ( 0.1) δ ( x − 4) The CDF is then given by integration, by definition, if P ( …
