A six-sided fair die can be modelled with a discrete random variable with outcomes 1 through 6, each with equal probability \textstyle\frac{1}{6}. The expected value is (1 + 2 + 3 + 4 + 5 + 6)/6 = 3.5. Therefore the variance can be computed to be: [Math Processing Error] T...

A discrete random variable is a random variable that can take on finite or countably infinite values. Suppose we haveS∈ Ωx: This is the probability thatSis the set containing the result. In the case of random variables, we look at the probability of a random variable having a certain ...
Random Variables can be either Discrete or Continuous:Discrete Data can only take certain values (such as 1,2,3,4,5) Continuous Data can take any value within a range (such as a person's height)Here we looked only at discrete data, as finding the Mean, Variance and Standard Deviation ...
