How many combinations are there with 11 digits?
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! Save this answer.
In your case, with 12 numbers, the number is 12x11x10x... x2x1=479001600. This number is called "twelve factorial" and written 12!, so, for example 4!=
With replacement means the same item can be chosen more than once. Without replacement means the same item cannot be selected more than once. 10 X 10 X 10 X 10 = 10,000 combinations are possible.
The number of combinations that are possible with a 13-digit number is 8,191. In statistics and probability, a combination is a group of objects in which order does not make a difference.
of ways of answering 11 questions = 211 = 2048 ways.
To multiply any two-digit number by 11, simply add the digits of the number together and then put this sum between the original two digits. For example, to quickly find the answer to 11 x 53, start by adding the two digits of the number 53 together to get 5+3=8.
The number of combinations of n objects taken r at a time is determined by the following formula: C(n,r)=n! (n−r)!
We get that it is possible to make 16,383 different combinations with a 14-digit number.
Combinations are a way to calculate the total outcomes of an event where order of the outcomes does not matter. To calculate combinations, we will use the formula nCr = n! / r! * (n - r)!, where n represents the total number of items, and r represents the number of items being chosen at a time.
This means that there are 21 combinations for choosing 2 elements from 7 distinct elements.
How many combinations can 20 numbers make?
Answer and Explanation: The number of combinations that are possible with 20 numbers is 1,048,575.
Therefore, the total number of possibilities is given by 9×9! =3265920. Hence, 9 digit numbers of different digits can be formed in 3265920 ways.
The answer to this question is 143. The LCM of 11 and 13 using various methods is shown in this article for your reference. The LCM of two non-zero integers, 11 and 13, is the smallest positive integer 143 which is divisible by both 11 and 13 with no remainder.
Answer and Explanation: The number of combinations possible with 24 numbers is 16,777,215.
Plugging in our numbers of n = 9 and r = 2, we get
9C2 = 9!
So we found that the number of ways of arranging 11 books on a shelf is 39916800.
Thus there are 39,916,800 permutations of 11 distinct objects.
It means the number of possible ways of 11 alphabets is 11!. It gives the number of ways which is 34650. Hence the total number of possible permutations in the word MISSISSIPPI are 34650.
Divisibility Rules for 11
If the difference of the sum of alternative digits of a number is divisible by 11, then that number is divisible by 11 completely.
Take the alternating sum of the digits in the number, read from left to right. If that is divisible by 11, so is the original number. So, for instance, 2728 has alternating sum of digits 2 – 7 + 2 – 8 = -11. Since -11 is divisible by 11, so is 2728.
Why does the 11 trick work?
If we multiply a 2-digit number by 11, we copy the ones digit to the ones digit of the product, add the ones and the tens digit and place the sum in the tens digit of the product, and then copy the tens digit to the hundreds digit of the product. For example, if we multiply 34 × 11.
Answer and Explanation: The number of combinations possible with 8 numbers is 255. We have the following formula for calculating the number of possible combinations from a set of x elements: Number of combinations possible with x elements = 2x - 1.
10 10 = 100 two digit combinations.
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.
So, no, the number of combinations is finite.
Hence, 8C4=8×7×6×51×2×3×4.
1234, 1243, 1423, 4123, 1324, 1342, 1432, 4132, 3124, 3142, 3412, 4312, 2134, 2143, 2413, 4213, 2314, 2341, 2431, 4231, 3214, 3241, 3421, 4321.

5C4 = 5. 5C5 = 1. This is exactly Pascal's triangle which we explored in the article on sequences.
12C2 = 12! / 2! ( 12-2)! = (12*11*10*9*8*7*6*5*4*3*2*1) / (2*1) (10*9*8*7*6*5*4*3*2*1) = (12*11) / (2 * 1) = 6*11.
What is 18c6?
18-Crown-6 is an organic compound with the formula [C2H4O]6 and the IUPAC name of 1,4,7,10,13,16-hexaoxacyclooctadecane. It is a white, hygroscopic crystalline solid with a low melting point.

118! ways to select 18 items. But we don't care about order. If we pick 18 items it does not matter what order we seected them in.
Number of possible 16-digit combinations = 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 × 10 = 1016 = 10,000,000,000,000,000.
Answer and Explanation: The number of combinations that are possible with 7 numbers is 127. In general, the formula we use to determine the number of combinations possible with n elements is as follows: Number of combinations possible with n elements = 2n - 1.
That is a total of 7 combinations.
Well there a lot of 10-digit numbers . The first place can't have the face value 0,so only 9 number can be put in it. The remaining 9 places can have 10 in each place. So there are 9*10^9 = 9,000,000,000 10-Digit numbers.
Since, 1 is the only common factor between 9 and 11. The Greatest Common Factor of 9 and 11 is 1.

Multiples of 11 are 11, 22, 33, 44, 55, 66, 77 … One thing that we are most certain about multiples of 11 is that they will always be a whole number. They result from any natural numbers multiplied by 11, which can be expressed as 11n.
Take the alternating sum of the digits in the number, read from left to right. If that is divisible by 11, so is the original number. So, for instance, 2728 has alternating sum of digits 2 – 7 + 2 – 8 = -11. Since -11 is divisible by 11, so is 2728.
As 11 is a prime number, it has only two factors, such as one and the number itself. Hence, the factors of 11 are 1 and 11, and the negative factors of 11 are -1 and -11.

…that there are infinitely many twin primes, or pairs of primes that differ by 2. For example, 3 and 5, 5 and 7, 11 and 13, and 17 and 19 are twin primes. As numbers get larger, primes become less frequent and twin primes rarer still.
Step-by-step explanation:
This means that the number DAD is at most equal to 198. So, D must be equal to 1. Note that D can not be zero as DAD is a three digit number. Clearly, LHS of this equation is a multiple of 11.
What is the skip counting of 11?
Count 11, 22, 33, 44, 55, 66, 77, 88, 99, 110, 121, 132 and so on.
A permutation is defined as an arrangement in a definite order of a number of objects taken, some or all at a time. Counting permutations are merely counting the number of ways in which some or all objects at a time are rearranged.
