You can make:
1 combination containing 0 digits,
7 combinations containing 1 digits,
21 combinations containing 2 digits,
35 combinations containing 3 digits,
35 combinations containing 4 digits,
21 combinations containing 5 digits,
7 combinations containing 6 digits, and
1 combinations containing 7 digits.
That makes 2^7 = 128 in all.
14 * * * * * Wrong! There are 15. 4 combinations of 1 number, 6 combinations of 2 number, 4 combinations of 3 numbers, and 1 combination of 4 numbers.
There is 1 combinations with 7 numbers in them,7 combinations with 1 or 6 numbers in them,21 combinations with 2 or 5 numbers in them,35 combinations with 3 or 4 numbers in them.Notionally, there is also one combination with no numbers in it.In all then, there are 128 ( = 27) combinations.There is 1 combinations with 7 numbers in them,7 combinations with 1 or 6 numbers in them,21 combinations with 2 or 5 numbers in them,35 combinations with 3 or 4 numbers in them.Notionally, there is also one combination with no numbers in it.In all then, there are 128 ( = 27) combinations.There is 1 combinations with 7 numbers in them,7 combinations with 1 or 6 numbers in them,21 combinations with 2 or 5 numbers in them,35 combinations with 3 or 4 numbers in them.Notionally, there is also one combination with no numbers in it.In all then, there are 128 ( = 27) combinations.There is 1 combinations with 7 numbers in them,7 combinations with 1 or 6 numbers in them,21 combinations with 2 or 5 numbers in them,35 combinations with 3 or 4 numbers in them.Notionally, there is also one combination with no numbers in it.In all then, there are 128 ( = 27) combinations.
The question, as stated, cannot be answered because there are only 26 = 64 combinations. The order of the numbers in a combination does make a difference so 134 is the same as 143 or 413 etc. There are 1 combinations each of 0 and 6 of the numbers, 6 combinations of 1 or 5 numbers, 15 combinations of 2 or 4 numbers, and 20 combinations of 3 numbers. The list includes the null combination - that is the combination consisting of none of the numbers.

how many combinations of 4 numbers are there in 7 numbers

26 = 64 combinations, including the null combination - which contains no 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.
Assuming that the six numbers are different, the answer is 15.
