## Probability Calculations - Chapter Summary and Learning Objectives

Mathematicians can determine the likelihood of an event happening by using probability calculations. These calculations take statistical data to determine how often something might occur and what factors may affect the likelihood of that event occurring. The lessons provided in this chapter give you an easy-to-follow guide that walks you through these probability calculations. You will also learn the definitions of all related terms. Therefore, this chapter can give you a deeper understanding of the following:

• Probability calculations with permutations and combinations
• The effects of dependent and independent events on probability calculations
• Understanding how different types of events change probability formulas
• Applying the 'At Least One' Rule and the Either/Or scenario to calculations

Lesson Objective
How to Calculate the Probability of Permutations Study factorials, go through the steps for determining the probability of a permutation, and examine a permutation example where events must happen in a certain order.
How to Calculate the Probability of Combinations Measure the amount of favorable outcomes and divide that by the amount of total outcomes, figure out the amount of events if no order is required, and show the relationship between these two concepts.
Probability of Independent and Dependent Events Practice calculating the probability of compound events by identifying dependent and independent events.
Probability Distribution: Definition, Formula & Example Go through the steps for building a probability distribution map that highlights all possible results pertaining to a statistical event.
Probability of Simple, Compound and Complementary Events Establish the formulas for calculating these three different types of events, then apply the formulas to practical examples.
Either/Or Probability: Overlapping and Non-Overlapping Events Evaluate statistical data, then determine the probability of either/or events with both non-overlapping and overlapping events.
Probability of Independent Events: The 'At Least One' Rule Delve into the definition for the process of complementary events, learn the 'At Least One' Rule, and use this information to determine independent event probabilities.
How to Calculate Simple Conditional Probabilities Point out the factors that create conditional probability, determine how the sequence of previous events to current events affects probability calculations, and practice calculating conditional probabilities.
