What is Probability?

In Mathematics, Probability theory is the study of chances. In real life, we predict chances depending on the situation. But Probability theory is bringing a mathematical foundation for the concept of Probability. For example, if a box contain 10 balls which include 7 black balls and 3 red balls and randomly chosen one ball. Then the Probability of getting red ball is 3/10 and Probability of getting black ball is 7/10. When coming to statistics, Probability is like the back bone of statistics. It has a wide application in decision making, data science, business trend studies, etc.

What is Baye's Theorem?

Bayes’ theorem is a mathematical formula used to calculate conditional probability. It is named after Reverend Thomas Bayes, who first formulated the theorem in the 18th century. The theorem provides a way to revise existing predictions or theories given new or additional evidence. It is often used in science, engineering, economics, and other fields to make predictions or decisions based on incomplete or uncertain information.
