Probability Rules/Disjoint and Independent Events

Probability Rules/Disjoint and Independent Events

Author: Al Greene

• Define what if means for events to be disjoint (mutually exclusive) and independent
• Present the rules of probability for disjoint and independent events, providing examples of each
• Demonstrate how to represent probability with venn diagrams
• Review key words such as “not”, “or” and “and” and how they can indicate different types of events in probability

This packet talks about disjoint and independent events. We show you examples of each type of event, probabilities for each kind, and detailed examples of each.
