(45 x 44 x 43 x 42 x 41 x 40 x 39)/(7 x 6 x 5 x 4 x 3 x 2) = 45,379,620 of them.
Could you generate a complete set of 6 number combinations from 45 numbers ?
There are an infinite number of combinations where this could be the answer.
By making a number tree that could have as many as 1,000,000 combos.
Most credit cards use 16 digit numbers. American Express uses 15. Either one of them allows for so very many more combinations than there are, or could reasonably be, active credit card accounts that a number chosen at random is unlikely to belong to an actual real account.
There are 21 combinations.

Oh honey, you're asking about combinations now? Buckle up, buttercup. There are a whopping 1,947,792 combinations of 6 numbers chosen from 1 to 36. That's a whole lot of possibilities, but hey, someone's gotta win the lottery, right?

To calculate the total number of possible combinations for a license plate using 3 letters and 3 numbers, we need to multiply the number of options for each character position. For letters, there are 26 options (A-Z), and for numbers, there are 10 options (0-9). Therefore, the total number of combinations can be calculated as 26 (letters) * 26 (letters) * 26 (letters) * 10 (numbers) * 10 (numbers) * 10 (numbers) = 17,576,000 possible combinations.

Simple enough to solve. The answer is a power of two. Assuming you have two possible digits, say for example, 3 and 4, then you simply have to multiply it by how many numbers you want to get the total number of combinations. Each number can be 3 or 4 in this case, and you have 5 numbers. That's two to the fifth. Five combinations of any two numbers. 2x2x2x2x2. The answer is 32 combinations.
Infinite. If numbers can be repeated, the list could go on nonstop.
To calculate the number of combinations of 5 numbers possible from 1 to 20, we use the formula for combinations, which is nCr = n! / (r!(n-r)!). In this case, n = 20 and r = 5. Plugging these values into the formula, we get 20! / (5!(20-5)!) = 20! / (5!15!) = (20x19x18x17x16) / (5x4x3x2x1) = 15,504 possible combinations.
You could make 10*10*10*26*26*26 combinations, or 17576000 combinations.
There is no single answer to that. A lot of combinations of 6 numbers could have a mean of 18.5, as any 6 numbers that add to 111 could.
