Random variable: Let S be the sample space associated with a given random experiment.
Then, a realvalued function X which assigns a unique real number X(w) to each w ∈ S, is called a random variable.
A random variable that can assume only a finite number of values is called a discrete random variable.
Probability distribution: If a random variable X takes values with respective probabilities then,
is known as the probability distribution of X.
