3 Proven Ways To Random Variables And Its Probability Mass Function (PMF)
The next theorem gives a formula for the variance that is often easier than the definition when performing computations. We have seen that \(X = \sum_{i = 1}^n X_i\), where \(X_i\) are independent Bernoulli random variables. The subscript $X$ here indicates that this is the PMF of the random variable $X$. g. For two random […]
