The answer is 3 * 3 * 3 *3. Since there are only 3 numbers for each spot then the answer is = 81 different combinations.
If you were to add a 0 in the mix and it was a 4 digit number the answer would be 4 * 4 * 4 * 4 = 256 different combinations. As you can see by adding a single extra option the combination becomes much harder to guess. I was working on a problem with my daughter that is 4 teams can place 1st, second, third or fourth; how many different ways can the teams place. I am coming up with 24, but am not sure that is the answer. I am pretty sure the formula is 4 * 3 * 2 *1 = 24; but I am not 100% confident in my answer. If anyone wants to confirm this for me I'd appreciate it.

How many number combinations are possible with three numbers?
If the numbers can be repeated and the numbers are 0-9 then there are 1000 different combinations.
What are the combinations of 1 through 10 with out using them twice?
There is 1 combination of all ten numbers, 10 combinations of one number and of nine numbers, 45 combinations of two or eight numbers, 120 combinations of three or seven numbers, 210 combinations of four or six numbers and 252 combinations of five numbers. That is 1023 = 210 - 1 in total.
How many number combinations are possible with the same three numbers?
Six * * * * * No, that is the number of PERMUTATIONS (not combinations). With 3 numbers, the number of combinations, including the null combination, is 23 = 8. With the three numbers 1,2 and 3, these would be {None of them}, {1), {2), {3}, {1, 2}, {1, 3}, {2, 3}, {1, 2, 3}.
What is an easy way to generate numbers with an odd number of factors?
Start with the factors. Multiply combinations of three prime factors, then combinations of five, then seven, etc. All generated numbers will be guaranteed to have an odd number of prime factors.
How many combinations can you make with three numbers?
You can make 6 combinations with 3 numbers. They are: 123 213 312 132 231 321 * * * * * NO! Those are permutations! In combitorials, the order does not matter so that the combination 123 is the same as the combination 132 etc. So all of the above comprise just 1 combination. With three numbers you can have 1 combination of three numbers (as discussed above), 3 combinations of 2 numbers (12, 13 and 23) 3 combinations of 1 number (1, 2 and 3) In all, with n numbers you can have 2n - 1 combinations. Or, if you allow the null combination (that consisting of no numbers) you have 2n combinations.
How many 3 number combinations can you make using the numbers 1-45?
Using the combination fuction, chose three numbers from 45 numbers. The answer is 14,190.
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 combinations of three digits can be made from the numbers 998?
Assuming you are treating each number as a number and not as an individual unit, the numbers you can make from these digits are 899, 989 and 998.
How many different three digit number combinations can be made with 0-9 with no repeat numbers when order of the number does not matter?
9
How many combinations are possible with 3 numbers?
I'm assuming they're three unique numbers. Thus, the first can be any of three, the second either of the remaining two, and the last is the last one left. Thus: combinations = 3 * 2 * 1 = 6 Or, more generally, the combinations of n numbers in such a problem is n factorial, denoted as "n!", which is every number from 1 to that number multiplied together.
What 3 numbers added make 13.65?

The numbers 2 6 18 54 are examples of what?
