# GMAT Probability Questions

If Atima studied for eight hours a day for 20 days for GMAT, what is the probability that she’d end up getting a good GMAT score? You won’t find a question exactly like that in your GMAT exam. Most students get confused with the probability questions in the quantitative section, if you are one of them, don’t worry. Here is all the information that you will need about probability questions for GMAT which can help you prepare better.

#### Things to Keep in Mind While Solving Probability Questions

Before getting started on how to solve probability questions, here are some essential things you should keep in mind while solving probability questions.The probability questions come in the quantitative section of the GMAT question paper to test your mathematical concepts. Here are some tips to understand probability questions better:

• Probability is the result of dividing the number of desired digits to the number of possible results. Probability is basically figuring out the chances of getting the desired number. You can figure out the probability of a situation such as expecting a heads while flipping a coin by dividing the number of desired digits to the number of possible results. The only two outcomes are heads and tails. So, the probability of getting heads is ½. Probability questions on the GMAT are not going to be this easy but this is a simple way of understanding it better.
• The probability of getting a certain result is the sum of two probabilities.The probability of getting one result or another means that you are looking for a single situation to happen. So, if you’re looking to find the probability of flipping a coin for getting heads or tails you have to find the probability of both. The probability of flipping a coin and getting the desired outcome is 50%. The probability of flipping a coin and not getting the desired outcome is also 50% so the probability of flipping a coin and getting heads or tails is ½ +½ =1.You should keep this point in mind while solving probability questions on the GMAT.
• The probability of getting two different results is the outcome of two different probability analysis. Finding two different probabilities with a similar pattern is only possible after finding the probability of two situations individually. For example, if you flip a coin twice, each time the coin will flip differently at its own pace. That way they won’t affect each other. So for finding the probability for two different results you have to find the individual probabilities.
• The probability of something not happening is one minus the probability of the outcome.

For finding the probability of something which won’t happen, you need to find the probability of something that will happen. If you’re trying to find the probability of flipping a coin and not getting heads, first try finding the probability of flipping a coin and getting tails. The probability of getting heads is 50 %. You have to minus the result by 1 so that the probability of getting the desired outcome becomes 50%.
