Prove that is throwing a pair of dice, the occurrence of the number 4 on the first die is independent of the occurrence of 5 on the second die.

Answer :

We are throwing two dice so,

Sample space S={(1,1),(1,2),(1,3),(1,4),(1,5),(1,6),






Sample space contains 36 elements,

A= Number four appears on first die


B=Number 5 on second die

B={(1,5), (2,5), (3,5),(4,5),(5,5),(6,5)}


Therefore A and B are independent events
