CONCEPT NOTE 2/LESSON 2: TYPES OF RANDOM VARIABLE TWO TYPES OF RANDOM VARIABLES • DISCRETE RANDOM VARIABLE- variable that can take on finite number of distinct values. Examples: 1. Number of heads obtained when tossing a coin thrice 2. The number of siblings a person has. 3. Number of student’s present in a classroom at a given time. • CONTINUOUS RANDOM VARIABLE- variable that can take an infinitely uncountable number of possible values, typically measurable quantities. Examples: 1. Time of pers
