Subjects : math, gmat

Instructions:

Answer 16 questions in 15 minutes.
If you are not ready to take this test, you can study here.
Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

1. Permutations: single source - order matters but only for a selection

2. Finding the probability of something happening at least once

3. What is a factorial?
For a problem that asks you to choose a number of items to fill specific spots - when each spot is built from a different source - all you have to do is multiply the number of choices for each of the spots. So if you were to have to pick from two app
To find the probability of a series of events you must multiply the probabilities of each individual events
To find all the possible permutations of the top 3/7 teams simply multiply the number of combinations for each spot in the standings. Comedy teams are possibilities for the first-place slot? If you said seven you're right how about the second slot? W
One of the most often used functions on the GMAT consists of a factorial a number followed by an exclamation point. I factorial is the product of a positive integer and all the positive integers less than that number. the only counter intuitive facto

4. Combination problems
To find all the possible permutations of the top 3/7 teams simply multiply the number of combinations for each spot in the standings. Comedy teams are possibilities for the first-place slot? If you said seven you're right how about the second slot? W
When you are trying to find the probability that a or B will happen you add the probability of each event together
Here's a good clue: permutation problems usually ask for arrangements. Combination problems usually ask for group's
For a problem that asks you to choose a number of items to fill specific spots - when each spot is built from a different source - all you have to do is multiply the number of choices for each of the spots. So if you were to have to pick from two app

5. The probability that both a and B will both happen
When you are trying to find the probability that a or B will happen you add the probability of each event together
For a problem that asks you to choose a number of items to fill specific spots - when each spot is built from a different source - all you have to do is multiply the number of choices for each of the spots. So if you were to have to pick from two app
Six horses are running in a race. How many different groups of horses could make up the first three finishers. To find the number of combinations first find the number of permutations if six horses run the race and we are interested in the top three
To find the probability of a series of events you must multiply the probabilities of each individual events

6. The probability that a or B will happen
The basic probability formula equals the number of outcomes you want divided by the total number of possible outcomes. For example if you rolled a six sided dice one time what is the probability that it would land with either of the two side facing u

A type of GMAT problem that requires an equation is the work problem. It is easy to spot because it's always involves two people or factories or machines working at different rates. In this problem the trick is not to think about how long it takes to
When you are trying to find the probability that a or B will happen you add the probability of each event together

7. What is a function?
A function is basically a set of directions. To solve the function problem on the GMAT you essentially take the set of instructions and apply it to whatever numbers you are given

Any problem that mentions planes trains cars bicycles distance miles per hour for any other travel related terminology is asking you to write an equation based on the formula rate multiplied time equals distance. This equation can also be written as

8. Finding the probability that something will not happen

9. What is the rate multiplied by time equals distance formula?

For a problem that asks you to choose from the same source to fill specific spots - all you have to do is simply multiply the number of choices for each of the spots but the number of choices keeps getting smaller. For example three bath bowl teams p

To calculate the probability of at least one thing happening just use this equation: the probability of what you want to happen plus the probability of what you don't want to happen equals the 1.

12. What our work problems?

13. How do you crack a work problem?
To figure out the probability that something won't happen simply figure out the probability that it will happen and then subtract that fraction from the 1.

As soon as you see the word strove for travel make a little chart for yourself. Include the variables rate time distance and who is being analyzed.

15. Not sure if it's a permutation or a combination problem?

16. Combinations: single source - order doesn't matter
