WebExample 1: Suppose a pair of fair dice are rolled. Let X be the random variable representing the sum of the dice. Construct a discrete probability distribution for the same. Solution: The sample space for rolling 2 dice is given as follows: Thus, the total number of outcomes is 36. WebThe probability density function (" p.d.f. ") of a continuous random variable X with support S is an integrable function f ( x) satisfying the following: f ( x) is positive everywhere in the support S, that is, f ( x) > 0, for all x in S. The area under the curve f ( x) in the support S is 1, that is: ∫ S f ( x) d x = 1.
