## How many combinations of 5 colors are there?

You can choose each color as many times as you like. You have five colors to choose from for the first room, five for the second and five for the third. This gives a total of 5 × 5 × 5 = 125 possibilities.

x | yellow | red |

## How many combinations of colors are possible?

There are 18 combinations for this arrangement (3x3x2). Finally, each spot can be a different color (rby, ryb, bry..). There are 6 combinations for this arrangement (3x2x1).

## How do you calculate the number of possible combinations?

The formula for combinations is generally n! / (r! (n — r)!), where n is the total number of possibilities to start and r is the number of selections made. In our example, we have 52 cards; therefore, n = 52.

## How many combinations of 4 are there?

There are 10,000 combinations of four numbers when numbers are used multiple times in a combination. There are 5,040 combinations of four numbers when numbers are used only once.

## What 3 colors go well together?

To give you a feel of what does and doesn’t work, here are a few of our favorite three-color combinations:

- Beige, Brown, Dark Brown: Warm and Reliable.
- Blue, Yellow, Green: Youthful and Wise.

## How many ways can you arrange 3 things?

Therefore, the number of ways in which the 3 letters can be arranged, taken all a time, is 3! = 3*2*1 = 6 ways.

## How many combinations of 3 numbers are possible?

There are, you see, 3 x 2 x 1 = 6 possible ways of arranging the three digits. Therefore in that set of 720 possibilities, each unique combination of three digits is represented 6 times. So we just divide by 6. 720 / 6 = 120.

## How many combinations of 7 numbers are there?

The number of combinations that are possible with 7 numbers is 127.

## How many combinations of 7 items are there?

There are 7 ways of choosing the first, 6 ways of choosing the second and 5 ways of choosing the third. 7 *6*5=210. So you get 7 ∗6∗53∗2∗1 7 ∗ 6 ∗ 5 3 ∗ 2 ∗ 1 = 35 ways.

## How many combinations of 6 colors are there?

In other words, there are 6! = 720 different arrangements for these six colors. So, the number of combinations is 720 / 720 = 1.

## What is nPr formula?

In Maths, nPr and nCr are the probability functions that represent permutations and combinations. The formula to find nPr and nCr is: nPr = n!/(n-r)! nCr = n!/[r!

## How many combinations of the numbers 1 2 3 4 are there?

Explanation: If we are looking at the number of numbers we can create using the numbers 1, 2, 3, and 4, we can calculate that the following way: for each digit (thousands, hundreds, tens, ones), we have 4 choices of numbers. And so we can create 4 × 4 × 4 × 4 = 44 =256 numbers.

## How do you do 4 choose 3?

4 CHOOSE 3 = 4 possible combinations. 4 is the total number of all possible combinations for choosing 3 elements at a time from 4 distinct elements without considering the order of elements in statistics & probability surveys or experiments.
