How many combinations the numbers one two and three using each digit only once can I get?
6 - 123, 132, 213, 231, 312, and 321.
How many 3 digit combinations there 0-9?
The order of the digits in a combination does not matter. So 123 is the same as 132 or 312 etc. There are 10 combinations using just one of the digits (3 times). There are 90 combinations using 2 digits (1 once and 1 twice). There are 120 combinations using three different digit. 220 in all.
How may combinations are in 123?
To calculate the number of combinations in 123, we need to clarify what you mean by "123." If you are referring to the number "123," then there is only one combination. However, if you are referring to a set of three distinct items labeled 1, 2, and 3, then there are six possible combinations: {1, 2, 3}, {1, 3, 2}, {2, 1, 3}, {2, 3, 1}, {3, 1, 2}, and {3, 2, 1}.
Find three consecutive even integers that have a sum of 123?

How many combinations can you make with three numbers?
To calculate the number of combinations with three numbers, you would use the formula for combinations, which is nCr = n! / r!(n-r)!. In this case, n is the total number of numbers you have to choose from, and r is the number of numbers you are choosing. So, if you have three numbers to choose from, there would be 3C3 = 3! / 3!(3-3)! = 6 / (6*0!) = 6 / 6 = 1 combination.
