Answer 1

Unbiased Die :-
1.  All outcomes are equally likely. that is probability  P, P(1) = P(2) = P(3) = P(4) =  
     P(5) = P(6) = 1/6
2.  Sum of all probabilities is 1.

Biased Die :-
1.  Outcomes are not equally likely, they might be equal or might not be equal, it 
    depends on what extent dice is biased.

Answer 2

Answer:

A six-sided die is said to be unbiased if it is equally likely to show any of its six sides.

When an unbiased dice is thrown the sample space is S = {1, 2, 3, 4, 5, 6}

Total number of outcomes = 6
