What are all 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.

How many 2 number combinations are there in the numbers 1 to 9?

I also know that there are 100 combinations of two digits from 0-9, and 10 ombinations of one digit from 0-9. How do I know this? 10 10 = 100 two digit combinations. 10 10 10 = 1000 three digit combinations.

So there are 4 x 3 x 2 x 1 = 24 possible ways of arranging 4 items. Therefore I divide 5040 / 24 = 210. So there are 210 different combinations of four digits chosen from 0-9 where the digits don’t repeat.

How many 3 digit combinations can 4 numbers make?

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 possible combinations of 5 and 4 are there?

There are 5 ⋅ 4 possibilities that satisfy this. The third can be any of the 5, so there are 5 ⋅ 4 ⋅ 5 = 100 possibilities for the first case. In the second case, the first two digits are the same. There are 5 ⋅ 1 = 5 ways this can occur. In this case, the third digit must be different, giving you only 4 options to chose from.

How many possible combinations of numbers are there between 0-9?

Assume that the digits go from 0-9. If the possibilities are 0 to 9, there are 10 possible first nnumber combinations. If a second one was added, every 10 of those possibilities can ba matched with one of the first ones, so 10 (first set) ×10 (second set) =100 possibilities.
