MATH 103 Lecture Notes - Lecture 7: Venn Diagram, Black Cards, Typhoid Fever
Document Summary
Students use the addition rule to calculate the probability of a union of two events. This lesson builds off of the probability rules presented in lesson 6 and introduces the addition rule for calculating the probability of the union of two events. The general form of the rule is considered, as well as the special cases for disjoint and independent events. The use of venn diagrams is encouraged throughout the lesson to illustrate problems. Revisit the high school considered in the opening discussion of lesson 5. Use the venn diagram to highlight the pieces involved in answering the following questions, as the answers to each of these questions are used to determine the number of students in the band or in organized sports: Discuss how the number of students in band or sports would be calculated if the summary of the school was presented differently.
