## What is the probability of guessing a 4 digit PIN code?

Research suggests thieves can guess one in five PINs by trying just three combinations.

How easy would it be for a thief to guess your four-digit PIN.

If he were forced to guess randomly, his odds of getting the correct number would be one in 10,000—or, if he has three tries, one in 3,333..

## How many 4 digit combinations are there using 1 6?

1,296 possible combinationsFirst, we have six possible digits to use to form our number. Assuming we can reuse any of these, the answer is simply 6^4, or 1,296 possible combinations.

## How many combinations of the numbers 1 2 3 4 are there?

Explanation: 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.

## How many combinations can you make with 4 numbers without repeating?

24 combinationsIn your case you have 4 digits. So 4x3x2x1=24 combinations of all 4 digits with none repeating. Without repeating digits 24 four digit numbers can be made .

## How many combinations of 1 4 numbers are there?

For the third digit there are only 2 choices and for the last digit, one choice. Thus if you are not allowed to repeat a digit the number of possible 4 digit numbers you can construct from 1,2,3,4 is 4 3 2 1 = 24.

## How many 4 digit numbers can be formed if repetition is allowed?

Two ways to get the answer: 1. There are 9999 integers starting with 1 and ending with 9999. But the 999 integers starting with 1 and ending with 999 have less than 4 digits, so the desired number is 9999-999 or 9000 ways.
