Question

if X is discrete random variable then prove that var(ax+b)=a² var(x)​

Answer 1

Answer:

• The expected value of X is usually written as E(X) or m. So the expected value is the sum of: [(each of the possible outcomes) × (the probability of the outcome occurring)]. In more concrete terms, the expectation is what you would expect the outcome of an experiment to be on average.
