Answer:
Probability Distribution
Step-by-step explanation:
Probability Distribution determines the possibility that an outcome will occur in a random experiment.
The probability of a certain event is 1 and that of event that will never occur is 0.
The sum total of all probabilities of all outcomes in a random experiment is 1.
There are different types of probability distribution , namely: normal distribution, poison distribution, chi square distribution etc.
The distribution types are required for different purposes. For example, normal distribution estimates the probabilities of an outcome occuring for a given number of trials given the probability of each event in each trial.
