How many 4 number combinations are there in the numbers 0 to 9?

10,000 possible combinations

How many 9 digit number combinations are there?

The combinations would ignore digit order (thus 12 and 21 are the same.) Then you have 9 choices for the first digit and 8 choices for the second one. Making a total of 9*8= 72 combinations. However since each one has a reversible pair the answer is half that so 36.

How many different numbers can you make with 5 digits?

The number of 5-digit combinations is 10 5=100,000. So, one more than 99,999. You can generalize that: the number of N-digit combinations is 10 N. Now, this assumes that you count 00000 or 00534 as “5-digit numbers”.

How many 4 digit numbers contain at least one 8 or 9?

Therefore, we have 8 choices (1 to 9, except 3) for the first digit, and 9 choices (0 to 9, except 3) for each of the other 3 digits. Therefore, 8 * 9 * 9 * 9 = 5832 4-digit numbers are possible without a digit 3. Therefore, number of 4-digit numbers containing at least one digit 3: = 9000 – 5832 = 3168.

How many ways can you arrange 4 numbers?

What is the combination rule?

If the order doesn’t matter then we have a combination, if the order do matter then we have a permutation. One could say that a permutation is an ordered combination. The number of permutations of n objects taken r at a time is determined by the following formula: P(n,r)=n!

How many different eight digit phone numbers can be created using digits 0 to 9?
