4 of them. In a combination the order of the numbers does not matter.
As there are 26 letters in the alphabet. You can calculate the number of combinations by multiplying 26x26x26, giving you the answer 17576.
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
0000-9999 (10x10x10x10 or 104) = 10,000 possible combinations allowing for repeated digits. If you are not able to repeat digits then it's 10 x 9 x 8 x 7 or 5,040 possible combinations without repeated digits.
4 of them. In a combination the order of the numbers does not matter.
There are only five combinations: 1234, 1235, 1245, 1345 and 2345.
There are twelve possible solutions using the rule you stated.
Since the order of the digits does not matter there are only five combinations: 1234, 1235, 1245, 1345 and 2345.
Since a number can have infinitely many digits, there are infinitely many possible combinations.
As far as it is possible to tell, the answer is none.
35
There are few enough that if you write them down (combinations of 4 out of 6 ingredients), you can figure out all possible combinations and try all of them. 1234 1245 1246 1345 etc. Yes, there is a prince! And no, the order of ingredients does not matter.
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.
