Ch 18: ACT Math - Probability: Tutoring Solution

About This Chapter

The Math - Probability chapter of this ACT Prep Tutoring Solution is a flexible and affordable path to learning about probability. These simple and fun video lessons are each about five minutes long, and they teach all of the operations involving probability required for the ACT exam.

How it works:

  • Begin your review or other ACT math preparation work.
  • Identify the probability concepts that you're stuck on.
  • Find fun videos on the topics you need to understand.
  • Press play, watch and learn!
  • Complete the quizzes to test your understanding.
  • As needed, submit a question to one of our instructors for personalized support.

Who's it for?

This chapter of our ACT prep tutoring solution will benefit any student who is trying to learn about probability and earn acceptable scores. This resource can help students including those who:

  • Struggle with understanding combinations, permutations or any other probability topic
  • Have limited time for studying
  • Want a cost effective way to supplement their ACT preparation
  • Prefer learning ACT topics visually
  • Find themselves struggling with the probability portion of the review
  • Cope with ADD or ADHD
  • Want to get ahead in their ACT preparation
  • Don't have access to ACT review materials

Why it works:

  • Engaging Tutors: We make learning probability simple and fun.
  • Cost Efficient: For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.
  • Consistent High Quality: Unlike a live ACT prep tutor, these video lessons are thoroughly reviewed.
  • Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Complete your probability review on the go!
  • Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.

Learning objectives:

  • Learn to calculate the probability of independent events.
  • Find out how to determine either/or probability of overlapping and non-overlapping events.
  • Examine some real-world examples of simple, compound and complementary events.
  • Learn to calculate the probability of combinations and permutations.
  • Look at some real-world examples of independent and dependent events.
  • Review how to calculate a permutation.

Probability of Independent Events: The 'At Least One' Rule

1. Probability of Independent Events: The 'At Least One' Rule

Occasionally when calculating independent events, it is only important that the event happens once. This is referred to as the 'At Least One' Rule. To calculate this type of problem, we will use the process of complementary events to find the probability of our event occurring at least once.

Either/Or Probability: Overlapping and Non-Overlapping Events

2. Either/Or Probability: Overlapping and Non-Overlapping Events

Statistics is the study and interpretation of a set of data. One area of statistics is the study of probability. This lesson will describe how to determine the either/or probability of overlapping and non-overlapping events.

Probability of Simple, Compound and Complementary Events

3. Probability of Simple, Compound and Complementary Events

Simple, compound, and complementary events are different types of probabilities. Each of these probabilities are calculated in a slightly different fashion. In this lesson, we will look at some real world examples of these different forms of probability.

How to Calculate the Probability of Combinations

4. 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. Combinations are used to calculate events where order does not matter. In this lesson, we will explore the connection between these two essential topics.

How to Calculate the Probability of Permutations

5. 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. We'll also review what a factorial is. We will then go over some examples for practice.

Probability of Independent and Dependent Events

6. Probability of Independent and Dependent Events

Sometimes probabilities need to be calculated when more than one event occurs. These types of compound events are called independent and dependent events. Through this lesson, we will look at some real-world examples of how to calculate these probabilities.

Math Combinations: Formula and Example Problems

7. Math Combinations: Formula and Example Problems

Combinations are an arrangement of objects where order does not matter. In this lesson, the coach of the Wildcats basketball team uses combinations to help his team prepare for the upcoming season.

How to Calculate a Permutation

8. How to Calculate a Permutation

A permutation is a method used to calculate the total outcomes of a situation where order is important. In this lesson, John will use permutations to help him organize the cards in his poker hand and order a pizza.
