## How many combinations of 6 items are there?

64For any combination of items, each item is either included or not included in the combo.

That means each item has 2 possibilities for every combination.

For 6 items, that would make the number of combinations = 2^6 = 64..

## How many combinations are possible with 2 letters?

325 possible combinationsThere are 325 possible combinations with two letters. To determine this number of combinations, we use the fact that the alphabet has 26 letters….

## How many 3 letter combinations are possible from Aeiou?

The third letter can also be any one of 26, leading to 26 * 26 (or 26 ^ 2) combinations for each vowel. The total number of 3-letter combinations is then 5 * 26 * 26 = 3,380 combinations.

## How many combinations of 12 numbers are there?

Combinations. So 479001600 combinations are possible if repetition is not allowed. If repetition of digits is allowed then, 12^12 combinations are possible. So 8916100400000 combinations are possible if repetition is allowed.

## How many ways can a 5 letter word be arranged?

120 waysSince there are no repeating letters, and there are 5 total letters, there are 5!= 120 ways to arrange them.

## How many possible combinations of letters are there?

17576Since letters can be in any combination or permutation as long as they arent words as your question suggests, any letter can occur in any of the 3 slots thus the answer is simply number of letters in the alphabet to the power of 3, also commonly known as “cubed”. Thus, 26 x 26 x 26 or 26^3 which is 17576.

## How many unique license plates can there be?

The mathematical formula for six independent spaces with 36 options each is (36*36*36*36*36*36) total combinations. That comes out to 2,176,782,336 possible combinations of license plate. And since every state has their own license plates, that’s 2.1 billion cars possible per state.

## What is the formula of nPr?

Definition: nPr(n,r) = n! / (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! Returns a random value between 0 and 1.

## How do you do combinations on a calculator?

Combinations on the TI83 or TI84 calculatorStep 1: Type in the first number. In this case, the first number is 25.Step 2: Press [MATH] and go to the PRB menu. You can use the right arrow to select the menu at the top.Step 3: Select 3 nCr and press [ENTER] … Step 4: Type the second number and press [ENTER]

## How many 5 letter words can be formed if repetitions are allowed?

Explanation: The word “APPLE” has 5 letters in which “P” comes twice. If repetition is allowed, the number of words we can form = 4*4*4*4*4 = 1024.

## How many combinations are there with 26 letters and 10 numbers?

36Since there are 26 letters and 10 digits you have a total of 36 characters to choose from for each position. Starting from the left you can fill in the first position in 36 possible ways. For each of the 36 possibilities for the first character there are 36 possibilities for the second character.

## How do you calculate total possible combinations?

Remember that 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 number of items, and r represents the number of items being chosen at a time.

## How many ways can a 7 letter word be arranged?

50405040 is the number of ways to arrange 7 letters (alphabets) word “FLORIDA” by using Permutations (nPr) formula.

## 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 3 letter palindromes are there?

451 3There are 451 3-letter words that are palindromes.

## How many 5 letter combinations are there?

## How many ways can 6 letters be arranged?

720 arrangementsSo the six letters can be a combination of 6×5×4×3×2×1 letters or 720 arrangements.

## How many 4 letter combinations are there?

256reto wrote: How many different 4 letter combinations can be created from the letters A,B,C, and D? This is a case of number of arrangements possible with repetition. Thus you have 4 options each for the 1st,2nd,3rd and 4th letter giving you a total of 4*4*4*4 = 256 number of possible combinations.
