Act math practice exam12/25/2023 ![]() ![]() This question features conditional probability, which is key to the solution. Assuming that one of the officers CANNOT be chosen for the committee, what are the odds that Dustin is randomly chosen to represent his class? The class consists of 87 students, including a president, vice president, and secretary. Sometimes you may be asked to find the probability of finding a certain probability GIVEN that another condition has already occurred, which lowers the denominator for your probability.Ī class is in charge of selecting a representative for the prom committee. Again, keep replacement in mind as you are calculating! If we are calculating the probability of multiple events occurring at the same time, we multiply the probability of each event. If we are drawing multiple marbles and not replacing them, the denominator changes as we progress since there is a lower total. Remember to consider replacement if there are multiple events. When considering calculating basic probability questions, there are a few things you need to be aware of: A handy scientific calculator is a great way to make this process simple and fast. Sometimes probabilities as fractions are simplified, sometimes they are not. For instance, if we have a jar of marbles and we are looking at the probability of drawing a blue □ marble, take the total marbles as your denominator and the total number of blue marbles as the numerator. ![]() ![]() The most important thing to remember for this type of question is how many total possibilities there are and how many ways you can successfully draw what is tested. These are probably very familiar problems to you and will more than likely appear in the first 15 questions of the test. The first type of problem you will likely encounter regarding statistics and probability will involve basic probability. If you're new to how the ACT works, be sure to check out this article that summarizes what you will find on this test. In this guide, we will look at some of the central ideas you can expect to see on your ACT exam. For statistics and probability, you can expect to see 5-7 questions, totaling 8-12% of the total math portion of the exam. The good news is that ACT very clearly publishes the breakdowns of its exam per subject. This article will be going over several ACT strategies, tips, and tricks to help you make it through the statistics questions. Also, these same mathematical concepts appear on the ACT in the math section, so you are expected to know how to apply many of these concepts to make a good analysis and statistical decisions. What are the odds? Is this a fair game? What are the potential winnings? These are all questions that we often ask throughout our everyday life. ![]()
