Probability, combination, and permutation tests are very rare on the GRE, especially for Quantitative, but you should still spend some time understanding some of the deeper concepts in order to prepare for any test that requires you to apply them. Many people have the misconception that you will have to memorize certain probabilities in order to pass. That is certainly not the case.
Great example of this would be flipping a coin. If it lands heads up, then you’ve already won because it’s a fair game. If you flip the coin a few times and it lands heads down, that doesn’t mean that you were cheated or anything else.
Probability is based on statistical probabilities. If you were to ask someone who was a pro at statistics how likely a coin is to land heads up, they would tell you that you had an extremely high chance. If you were to ask them how likely a coin is to land heads down, they would tell you that there is only a slight probability that it will land heads up, so you probably won’t win. It’s all about statistical probability.
Probabilities change over time, because things like natural disasters, weather, and other factors can change a number of variables. You might get lucky and find out that you will pass your GRE exam because you took some time to learn how probability works.
Another good way to learn more about probability is to get a copy of a textbook that teaches you more about probability and see how it applies in a real exam. The best option for me personally was taking a course from Kaplan University because I wanted to go deeper in learning about the topic.
In the book, I learned a lot about the concepts, and I was able to apply them on the G GRE. Some topics covered in the course include what probability is, how to use it to your advantage on the exam, and what to expect on the exam. It definitely helped me a lot with my preparation.
Probabilities aren’t really that difficult to grasp once you understand them, but it does take some practice to become familiar with them and the concepts. If you have enough spare time, it might be a good idea to spend time with Kaplan University because they offer an entire course on the subject, which includes the most recent topics and techniques.
Probability is a great tool to use in order to increase your confidence and score. If you are nervous before any test because you’re not sure what you’re doing or how you’re going to do it, chances are that you’ll end up failing. This means that you’re not really prepared enough to pass the exam.
If you’re nervous before the exam because you’re worried that you’re going to mess up, chances are that you’re not going to do much better than your friends or the people who pass the exam without the slightest bit of nervousness. A lot of people make the mistake of thinking that they are better than everyone else because of how confident they feel about themselves, so they try to do too much and push too hard, and fail.
Don’t worry about this. If you want to become a better GRE taker, just relax and be happy that you took the test. It will show on the test, too.
Probabilites are a great way to get more confidence and also improve your score on the GRE. They are just something to keep in mind when you’re preparing for an exam.
