The answers are (B) UNIFORM probability model, and (A) NON-UNIFORM probability model.
What is probability?
It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
As we know, a uniform probability distribution means that the probability of all potential outcomes in the probability space is the same.
In a (B) UNIFORM probability model, the probability of each outcome occurring is the same. In a (A) NON-UNIFORM probability model, the probability of each outcome occurring is not the same.
Thus, the answers are (B) UNIFORM probability model, and (A) NON-UNIFORM probability model.
