Description
In this course, everything has been broken down into a simple structure to make learning and understanding easy for you.
Probability and statistics help to bring logic to a world replete with randomness and uncertainty. This course will give you the tools needed to understand data, science, philosophy, engineering, economics, and finance. You will learn not only how to solve challenging technical problems, but also how you can apply those solutions in everyday life and can solve many problems from the books for your exams.
With examples from our daily life and and from the famous books on these topics, you will gain a strong foundation for the study of statistical inference, stochastic processes, randomized algorithms, and other subjects where probability is needed.
As this course is specially designed for the University and High School Students who are facing difficulties in their studies and for those who want to boost up their skills in this field.
With this 16 Hours Probability and Statistics course,you can understand from very basic level and can become expert in this course.
