Complement and Addition Rule Practice

This interactive GeoGebra example is a probability practice tool that demonstrates the complement rule and the addition rule in probability theory. It visually and interactively shows how to compute P(A'), the complement of an event, and P(A∪B) using the addition rule P(A∪B)=P(A)+P(B)-P(A∩B). The construction uses the Random command to generate random data, with objects such as group1, group2, group3, group4 for organizing data, and buttons (button1, button2, button3) to trigger new problems or check answers. Variables like total, A, B store numerical values, while text objects (text1 through text16) display questions and step-by-step solutions. The complement and addition sections are handled by dedicated objects (complement, addition) with solution steps (csol1, csol2, asol1-asol4). This resource is suitable for high school or introductory college statistics courses, serving as a classroom demonstration or self-paced practice for mastering fundamental probability rules.
