View all practice tests in this course. Understanding Bar Graphs and Pie Charts In this lesson, we will examine two of the most widely used types of graphs: Calculating the Standard Deviation In this lesson, we will examine the meaning and process of calculating the standard deviation of a data set. Probability of Simple, Compound and Complementary Events Simple, compound, and complementary events are different types of probabilities. Probability of Independent and Dependent Events Sometimes probabilities need to be calculated when more than one event occurs.

Overlapping and Non-Overlapping Events Statistics is the study and interpretation of a set of data. Probability of Independent Events: How to Calculate Simple Conditional Probabilities Conditional probability, just like it sounds, is a probability that happens on the condition of a previous event occurring. Formula and Example Problems Combinations are an arrangement of objects where order does not matter. How to Calculate the Probability of Combinations To calculate the probability of a combination, you will need to consider the number of favorable outcomes over the number of total outcomes.

How to Calculate a Permutation A permutation is a method used to calculate the total outcomes of a situation where order is important. How to Calculate the Probability of Permutations In this lesson, you will learn how to calculate the probability of a permutation by analyzing a real-world example in which the order of the events does matter. Tree Diagrams in Math: What is Range in Math? Formula of Sample Space in Math In this lesson, we explore what is sample space, how it is related to probability and the formula to use to find it when given probability problems.
