How many 5 digit combos in 30 numbers?
The answer will depend on how many digits there are in each of the 30 numbers. If the 30 numbers are all 6-digit numbers then the answer is NONE! If the 30 numbers are the first 30 counting numbers then there are 126 combinations of five 1-digit numbers, 1764 combinations of three 1-digit numbers and one 2-digit number, and 1710 combinations of one 1-digit number and two 2-digit numbers. That makes a total of 3600 5-digit combinations.

How many 6 digit combinations are there in 20 numbers?
To calculate the number of 6-digit combinations using 20 numbers, you can use the formula for combinations, which is nCr = n! / r!(n-r)!. In this case, n = 20 (the total number of numbers) and r = 6 (the number of digits in each combination). Plugging these values into the formula gives us 20C6 = 20! / 6!(20-6)! = 38,760 unique 6-digit combinations that can be formed using 20 numbers.

If using numbers 0 through 9 how many different 2 digit combinations can be made?
If there are no restrictions on duplicated numbers or other patterns of numbers then there are 10 ways of selecting the first digit and also 10 ways of selecting the second digit. The number of combinations is therefore 10 x 10 = 100.
