Independence is a fundamental notion in probability theory as in statistics and the theory of stochastic processesTwo events are independent statistically independent or stochastically independent if informally speaking the occurrence of one does not affect the probability of occurrence of the other or equivalently does not affect the odds.

First we will find the z-score associated with a score of 84. Probability theory is an interesting area of statistics concerned with the odds or chances of an event happening in a trial eg getting a six when a dice is thrown or drawing an ace of hearts from a pack of cards.
