Description

This course is for beginners who want to learn the fundamentals of probability.

The course begins with some basic laws of probability, and moves on to introduce the addition laws or theorems on probability.

These videos are designed to give a clear understanding of the proofs for addition laws or theorems on probability. Building on probability concepts that begin in the middle grades, students of K-11 and K-12 grades use the language of set theory to expand their ability to extend the concept of addition theorems to problem solving.

The lectures also cover some results on probability of occurrence of a complementary event.

Also a brief discussion on odds of an event followed by a theorem on the same is covered in two of the videos. Appropriate examples are also discussed.

These videos will remove the doubts and clear the confusion between the terms "probability" of an event happening and "the odds" of an event.

The videos can be completed in an hour.

Five interactive quizzes are added to the course. The quizzes are of two types.

Type one is multiple choice quiz where only one of the answers provided is correct. and

Type two is true or false quiz. The problems in these quizzes should give you an idea about the type of problems that you can encounter in your exams.

All questions are not direct. The solutions to some of them can be obtained by using more than one law or theorem.

There is no time limit for the quiz. You can take the quiz at your own pace. However, it is advisable that a time limit be set in order to judge your speed of completing the quiz. This will help you in the preparation for actual examination. There is a score keeper for the quiz to track your progress

Get started and gain confidence to state and establish the addition theorems on probability and use them in solving problems by enrolling into this course!

Good Luck!

In this video the following problem is solved:

A coin and a die are thrown. Event A is "getting a tail". Event B is "getting a head and an even number".

Event C is "getting an even number".

(1)Find P(A), P(B), P(C), P(Ac ), P(Bc ),P(AUB), etc.

(2)Verify that P(A) + P(Ac ) = 1 and P(B) + P(Bc ) = 1

(3) Are A and B mutually exclusive ? Verify that P(AUB) = P(A)+ P(B)

(4) Are A and C mutually exclusive ? Verify that P(AUC) = P(A)+ P(C) - P(A intersection B)
