## How many ways can 123 be arranged?

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..

## How many combinations of 6 numbers are there in 59?

45,057,474The number of combinations possible with 6 numbers between 1 and 59 is 45,057,474.

## How many combinations are there in a 10 digit number?

10,000,000,000If repetition is allowed, then the number of permutations of 10 digits is 10,000,000,000.

## What is nPr formula?

nPr(n, r) The number of possibilities for choosing an ordered set of r objects (a permutation) from a total of n objects. Definition: nPr(n,r) = n! / (n-r)! nCr(n, r)

## How many combinations of 5 numbers are there?

120Hence there are 2 choices for the fourth digit and only 1 choice for the fifth digit. 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.

## How many possible combinations of 3 items from a group of 5 are possible?

10 possible combinationsSo 5 choose 3 = 10 possible combinations.

## How many combinations of 5 colors are there?

125 possibilitiesYou 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.

## What are the 4 number combinations?

There are 10,000 possible combinations that the digits 0-9 can be arranged into to form a four-digit code. Berry analyzed those to find which are the least and most predictable.

## What are the possible combinations of 6 numbers?

For any group of 6 numbers and letters, there are a possible 720 different permutations or combinations that can be made.

## How many combinations of 7 numbers are there?

127Answer and Explanation: The number of combinations that are possible with 7 numbers is 127.

## How do you calculate odds?

Divide the number of events by the number of possible outcomes.Determine a single event with a single outcome. … Identify the total number of outcomes that can occur. … Divide the number of events by the number of possible outcomes. … Determine each event you will calculate. … Calculate the probability of each event.More items…•

## How do you figure out the number of possible combinations?

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. To calculate a combination, you will need to calculate a factorial.

## How many different combinations of 12345 are there?

=120. Combinations of 5 digits= 5!/(0!)( 5!) =1.

## How many numbers can be made with 6 digits?

If you are just using the digits from 1 to 6, the answer would be 6*5*4*3*2*1 = 720, because you have 6 choices for the units digit, and then 5 choices left for the tens, and then 4 choices left for the hundreds and so on.
