In this lesson, we are going to be talking about the addition rule for disjoint events. First, we will see again what disjoint events mean and then we will talk briefly about the meaning of the word or because it has a slightly different meaning in statistics than in regular life. Then we will talk about how to calculate the probability of A or B and that method is going to be the addition rule. We are going to talk about the addition rule when A and B are disjoint events, as well as when they are not disjoint events.
Lecture Slides are screen-captured images of important points in the lecture. Students can download and print out these lecture slide images to do practice problems as well as take notes while watching the lecture.
This book provides a clear and methodical approach to essential statistical procedures. It clearly explains the basic concepts and procedures of descriptive and inferential statistical analysis. This book features a new emphasis on expressions involving sums of squares and degrees of freedom as well as a stronger stress on the importance of variability.
