## How many combinations of 10 items are there?

The answer is known as a factorial, which for the number 1234567890 of 10 total digists = 10.

= 1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9 x 10 = 3,628,800 – a little under 3.3 million possible combinations of numbers .

Its a fascinating subject..

## How many combinations of 5 are there?

Thus you have made 5 × 4 × 3 × 2 1 = 120 choices and there are 120 possible 5 digit numbers made from 1, 2, 3, 4 and 5 if you don’t allow any digit to be repeated. Now consider the possibilities with 13 as the first two digits.

## What is nPr formula?

Definition: nPr(n,r) = n! / (n-r)! nCr(n, r) The number of different, unordered combinations of r objects from a set of n objects. Definition: nCr(n,r) = nPr(n,r) / r!

## How many combinations of 50 numbers are there?

All Possible Number Combinations For 5/1-50 Lottery Games Included with Your Order: All Possible 5/50 Number Combinations. Total Combinations – 2,118,760.

## How many combinations can you make with 12 items?

479001600In your case, with 12 numbers, the number is 12x11x10x… x2x1=479001600. This number is called “twelve factorial” and written 12!, so, for example 4!= 4x3x2x1=24.

## How many combinations of 3 items are there?

3*3*3=27 unique possibilities.

## How many combinations of 6 items are there?

720 possible combinationsWith 1 item there are 6 possibilities with 2 you only have 5 choices after the first if you don’t repeat the same item. So for 6 items the equation is as follows 6*5*4*3*2= 720 possible combinations of 6 items.

## How many combinations are there with 2 items?

There are 3 numbers. So the number of permutations (arrangements) of three items equals 1 x 2 x 3 = 6. Thus, there are six permutations per combination. The number of combinations therefore is 6480 / 6 = 1080.

## How many combinations are there with 11 numbers?

99 combinations2! See for 11 numbers there can be 9 ways for each number for 1st nine places since 0 can’t be the fist number and next two are repeated from 10 numbers hence 10!/2! So 99 combinations have 10!/2! Permutations hence total ways are 99*10!/2!

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

To calculate combinations, we will use the formula nCr = n! / r! * (n – r)!, where n represents the number of items, and r represents the number of items being chosen at a time.

## 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 4 items are there?

You multiply these choices together to get your result: 4 x 3 x 2 (x 1) = 24. Combinations and permutations are often confused by students – they are related, but they mean different things and can lead to totally different interpretations of situations and questions.

## How many combinations of 8 items are there?

With 8 items on your menu, the number of possible combinations will be 28 = 256. And if you bought all 8 items, and tried to arrange them in different orders on your tray, the number of arrangements (‘permutations’) would be 8! = 40320.

## How many combinations of 100 numbers are there?

Given 100, choose 99, there are 100 combinations. Given 100, choose 98, there are 161,700 combinations. The number of combinations gets bigger fast. 100, choose 95, is over 7 million combinations.

## How do you calculate permutations?

The number of permutations of n objects taken r at a time is determined by the following formula: P(n,r)=n! (n−r)! A code have 4 digits in a specific order, the digits are between 0-9.

## What are all the possible combinations of 1234?

If you wager on 1234 boxed, you would win if any of the following combinations were drawn: 1234, 1243, 1324, 1342, 1423, 1432, 2134, 2143, 2314, 2341, 2413, 2431, 3124, 3142, 3214, 3241, 3412, 3421, 4123, 4132, 4213, 4231, 4312, or 4321.
