# A pair of fair dice, one blue and the other gray, are rolled. Let A be the event that the number face

To determine

To prove that P(A|B)=P(A)and P(B|A)=P(B).

Explanation

Given information:

A pair of fair die one blue and other grey is rolled. Let A= the event that face up on blue die is 2 and B= the event that face up on grey die is 4 or 5.

Calculation:

A={21,22,23,24,25,26}N(A)=6P(A)=636=16 {total outcome =36}B={14,15,24,25,34,35,44,45,54,55,64,65}N(B)=12P(B)=1236=13AB={24,25}N(AB)=2P(
