There are 5,461,512 such combinations.
There are infinitely many numbers and so infinitely many possible combinations.
10.
There are 120 permutations and 5 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.

120 5x4x3x2x1=120
The answer is 31C5 = 31!/[26!5!] = 169,911
The number of combinations is nCr = (59*58*57*56*55)/(5*4*3*2*1) = 5006386
There are a huge number of combinations of 5 numbers when using the numbers 0 through 10. There are 10 to the 5th power combinations of these numbers.
Assuming there are 5 check boxes and the respondent may check any number of them, the answer is 25 = 32 combinations.
