Understanding probability
My lessons will make understanding probability very straightforward. Probability which is the likelihood of something happening is used daily in our conversation.
For example, soon or later, most of us have asked ourselves the following questions:
What is the likelihood that it is going to rain tomorrow?
What is the likelihood that when flipping a coin, it will land on tail?
What is the likelihood that a patient will die after a surgery?
The second question above is easier to answer.
Since a coin has two sides, it has 50% chance of landing on tail.
It also has 50% chance of landing on head
The first and the third question are not easy to answer since they may require a solid understanding of the topic.
My goal is to introduce you to the topic and help you develop and appreciation.
Any serious study start with a solid understanding of the fundamental counting principle, combination, and arrangement, which show you how to count
Therefore, I strongly encourage you to start studying these. They will make understanding probability a lot easier.
