There are 10,000 possible combinations that the digits 0-9 can be arranged into to form a four-digit code..
Similarly, what are all the possible combinations of 4 numbers 0 9?
For each choice of the first two digits you have 10 choices for the third digit. Thus you have 10x10x10 = 1000 choices for the first three digits. Finally you have 10 choices for the fourth digit and thus there are 10x10x10x10 = 10 000 possible 4 digit combinations from 0-9.
Beside above, how many 4 digit numbers can be formed with the 10 digits? 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.
Besides, what are all possible combinations of 4 numbers?
If repetition is allowed, you find the product of the number of possibilities for each digit, in this case, there are four possible digits (4,5,8,7) to choose from and 4 places to put them: Which are: 4444 4445 4448 4447 4454 4455 4458 4457. 4484 4485 4488 4487 4474 4475 4478 4477.
How many 5 digit combinations are there using 0 9?
So, the number of ways we can fill the 5th place is 9. For the 4th place, we can have any digit from 0–9. Same goes for the 3rd, 2nd as well as the One's place. Finally we can multiply them and get your answer which is 9*10*10*10*10 which results in 90000.
