There are:
8C6 = 8!/6!(8-6)!
= (8 x 7)/(2 x 1)
= 28.
7 of them. Remember, that in a combination the order of the numbers does not matter.
They are called combinations!
120 WRONG! That is the number of PERMUTATIONS. In the case of combinations, the order of the numbers does not matter, so there is only 1 5-number combination from 5 numbers.
If order doesn't matter, 15 combinations and if order does matter, 360 combinations are possible.
There is only one combination since the order of the numbers in a combination does not matter.

4 of them. In a combination the order of the numbers does not matter.
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.
10 Combinations (if order doesn't matter). 3,628,800 Possiblilities (if order matters).
You can get only four combinations: They are: 11, 118, 119 and 1189. In a combination, the order of the digits does not matter.
They are called combinations!
If order doesn't matter, 15 combinations and if order does matter, 360 combinations are possible.
120 WRONG! That is the number of PERMUTATIONS. In the case of combinations, the order of the numbers does not matter, so there is only 1 5-number combination from 5 numbers.
Since the order of the numbers (digits) does not matter in a combination, there is just 1.
There is only one combination. The order does not matter in a combination.
Since the order of the digits does not matter there are only five combinations: 1234, 1235, 1245, 1345 and 2345.
