Just 4: 123, 124, 134 and 234. The order of the numbers does not matter with combinations. If it does, then they are permutations, not combinations.
As there are 26 letters in the alphabet. You can calculate the number of combinations by multiplying 26x26x26, giving you the answer 17576.
4 of them. In a combination the order of the numbers does not matter.
if i got everything right, its 1000
It depends on whether the order of the numbers is important or not. For example, if 123456 is seen as a different code to 213456 then there are many more possible solutions.If the order is unimportant, the number of possible combinations is equal tobinomial coefficient(15,6) = 5005If the order is important, then the number of possible permutations is equal to15! = ~1.3x1012
Since a number can have infinitely many digits, there are infinitely many possible combinations.
35
There are infinitely many numbers and so infinitely many possible combinations.
2^n possible combinations
If repeats are allowed than an infinite number of combinations is possible.
There are countless possible liquid combinations, depending on the types of liquids you are considering (water, juice, alcohol, etc.) and how many you want to mix together. The number of combinations would be exponential, as each additional liquid increases the number of possible combinations exponentially.
61
The number of combinations - not to be confused with the number of permutations - is 2*21 = 42.

There are only five combinations: 1234, 1235, 1245, 1345 and 2345.
If the numbers can be repeated and the numbers are 0-9 then there are 1000 different combinations.
