Question

What's the difference between biased and unbiased Die?

Answer 1

Difference between biased and unbiased dice:

In a biased die, the outcomes are not equally likely. So that the probability of coming to each face is not equal.

An unbiased dice means that there is an equal probability of occurrence of any of the faces when the dice is rolled.

So that, when we rolled an unbiased dice, the probability of coming to each face is equal.

$\therefore P\left(1\right)=P\left(2\right)=P\left(3\right)=P\left(45\right)=P\left(5\right)=P\left(6\right)=\frac{1}{6}$

Hence, In the biased die, the outcomes are not equally likely and in the unbiased die, outcomes are equally likely.
