Answer #1

Independence of Random Variables: -

  • The Concept of Independent Random variables is similar to independent of events.
    • If we can say Variables A and B are independent then we have

P(A∩B) = P(A)*P(B)

  • In some situations we can say Random variables are independent of each other because of the two random variables do not have similar features.

Examples of Independence of Random variables: -

  • Toss a Fair Coin 'n' number of times
    • each toss is independent of the other.
  • Roll a Dice
    • As like coin experiment here also every experiment is independent of other.
    • we can not expect the future experiment result based on previous experiment result.
  • length of the time waiting at the bus stop for a 2 buses.
  • Student Attendance % in a class.
