1. Random Variables#

  • In probability,we calculate the probablity(chances of outcomes)

  • We need to assign a number to each outcome

  • Function which does this is called random variable

  • For example,in below example :

    • I clicked on any hexagon (click means outcome) and then gave it a number

    • Repeated it for all the outcomes

      • We now have random variable

2. Types of Random Variable#

  • Discrete Random Variable

    • A discrete random variable has a finite/countable number of possible values.

  • Continuous Random Variable

    • A continuous random variable has a infinite/non-countable number of possible values
