## How many 5 digit numbers can be formed using 0 9 with repetition?

Since every **number can** be repeated on any place so in each of the **digit’s** place there are totally 10 possible **numbers** i.e. 0 to 9. 10*10*10*10*10 = 10^ **5**.

## How many 5 digit numbers can be formed using 1/9 if no digit can appear more than twice?

Overall, there are 25,200 **5 digit numbers with no digit** repeating **more than twice**. This is still only just about 1/4th of 90,000 possible **5 digit numbers**.

## How many number of 5 digits can be formed?

Repetition of **digits** is allowed. ∴ Each place out of unit, 10th, 100th and 1000th **can** be filled in **5** ways. Total **numbers** =4×**5**×**5**×**5**×**5**=2500.

## How many possible combinations are there for a 5 digit number?

Assuming the first digit can be 0, there are **100000** such combinations (because after chopping off the initial zeroes, each combination gives a number between 0 and **99999** and there are obviously **100000** of those).

## How many 10 digit number combinations are there?

If you have 10 digits then the maximum number possible is: **9,999,999,999**. Since the sequence starts at we need to add 1. So **10,000,000,000** (**10 billion**). That is how many numbers can be represented in 10 digits, it is not the number of phone numbers possible.

## How many 6 digit combinations are there using 0-9?

**There** are 900000 **possible** ways to get **6 digit** numbers **using 0 – 9**.

## How many numbers are there in 5?

The largest 5 digit number is **99999**. **99999** minus **10000** is **89999,** but since you have a zero-based count, you have to add 1. That means there are a total of 90,**000** different 5 digit numbers. Hence, there are 90,**000** 5-digit numbers.

## How many 4 digit numbers can be formed in which all the digits are different?

There will be as **many 4**–**digit numbers** as there are permutations of 5 **different digits** taken **4** at a time. 5 5 **4** 5 1 P!!!! = 5 × **4** × 3 × 1 × 1 = 120 Among the **4**–**digit numbers formed** by using the **digits**, 1, 2, 3, **4**, 5, even **numbers** end with either 2 or **4**.

## How many numbers of 5 digits can be formed with the digits 0 2 3 4 and 5 if the digits may repeat?

{, **2**, **3**, **4**, **5**} –> 96 **5**–**digit numbers** possible with this set. **If 0** is not included: {1, **2**, **3**, **4**, **5**} –> 120 **5**–**digit numbers** possible with this set. {1, **2**, **3**, **4**, 6} –> 120 **5**–**digit numbers** possible with this set.

## How many five digit number can be made from the digits 1 to 7 if repetition is allowed?

How **many five**–**digit numbers can be made from the digits 1 to 7 if repetition is allowed**? Explanation: **7**^{5} = 16807 ways of making the **numbers** consisting of **five digits if repetition is allowed**.

## How many 5-digit numbers can be formed which are divisible by 3?

Therefore, we have a total of 120 + 96 = 216 ways to form a **five**–**digit number** that is **divisible by 3**.

## 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.

## How many 6 digit are there in all?

∴ there are **900,000 6**-digit numbers in all.
