For this post, we will be dealing with the topic of probability. In the video, we cover how to find the probability of separate events that come right after each other. We also cover how to use complements, or the “opposite” of an event, to find probability.
The example used in the video will be based off the ACT math problem below:

This is the practice exercise we will work out in the video:
This practice problem is considered a HARD difficulty problem.
For this post, we will cover ACT math examples that involves the arithmetic mean. One type of problem that the ACT likes to use is to start off with a group of scores with a known average. Next, a score is added or subtracted from the original scores, and then the new average of the scores has to be calculated.
Our examples in the video will be based off the following ACT math problem below:

These are the two practice exercises we will work out in the video:
The practice problems are considered MEDIUM difficulty problems.
