# How to calculate possible combinations

## What is the easiest way to calculate combinations?

## How many combinations of 4 items are there?

I.e. there are 4 objects, so the total number of possible combinations that they can be arranged in is 4! = 4 x 3 x 2 x 1 =

**24**.## How do you calculate possible outcomes?

To find the total number of outcomes for two or more events,

**multiply the number of outcomes for each event together**. This is called the product rule for counting because it involves multiplying to find a product.## How many combinations of 3 items are there?

3*3*3=

**27 unique possibilities**.## How many combinations of 8 items are there?

40,320 different combinations

Note: 8 items have a total of

**40,320 different combinations**.## How many combinations of 5 items are there?

Note that your choice of 5 objects can take any order whatsoever, because your choice each time can be any of the remaining objects. So we say that there are 5 factorial = 5! = 5x4x3x2x1 =

**120 ways**to arrange five objects.## How many combinations of numbers are there between 000 and 999?

The smallest 3 digit number I have is zero, written 000 and the largest is 999 and I have ever integer between 000 and 999. Thus I have 1,000 numbers or

**1,000 possible combinations**.## How many combinations of 7 items are there?

7*6*5=

**210**.## How many combinations are there with 11 numbers?

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 many possible combinations are there for a 3 digit lock?

A standard 3-digit lock has

**999 possible combinations**, which is why the 4- digit locks cost a bit of a step more money, as they have 9999 possibles. One very important thing to remember is the resetting of this lock to something much different from your actual combo, when you lock it.## How do you figure out how many combinations a lock has?

## How do you calculate repetition combinations?

The number of k-element combinations of n objects, with repetition is

**Cn,k = Cn+k-1,k = (n + k − 1 k ) = ((n k ))**. It is also the number of all ways to put k identical balls into n distinct boxes, or the number of all functions from a set of k identical elements to a set of n distinct elements.## How do you break a 3 combination lock?

## How many combinations are there with 3 letters and 3 numbers?

How many license plates can be made consisting of 3 letters followed by 3 digits? Each of the three letter combinations can be combined with any of the three number combinations so the total is 17,576 x 1000 =

**17,576,000 different combinations possible**.## What is the most common 3 digit number?

**100**statistically seems likely as the most popular three-digit number.

## How do you guess a 3 digit combination lock?

## How do you solve a combination lock?

**Standard Instructions for Opening a Combination Lock**

- Turn right three times. Stop at First Digit.
- Turn left one full turn passing 1st number and stop at Second Digit.
- Turn right and stop at Third Digit. Pull shackle. Profit.
