Thanks,

It depends whether you count each individual's response as a variable or whether you simply add up the total yes's and no's.

I added them up to give totals etc..

Exactly - I was just explaining why there were two answers.

Yeah, I know

I actually didn't think of the other one so I was basically stating my moronity!

Your answer is just as valid, I think. Depends whether you treat each answer individually, or are just interested in totting up the number of yeses and nos. In the latter case, the answer is 26, as you said.

You may have put it more eloquently than me a few posts up.

I mean like it could be:

1: YES
2: YES
3: YES
4: NO
5: NO
6: YES
7: YES
8: YES
9: YES
10: YES
11: YES
12: YES
13: YES
14: YES
16: YES
17: YES
18: YES
19: NO
20: YES
21: YES
22: YES
23: YES
24: NO
25: YES

So that's one combination... but then it could be:

1: YES
2: YES
3: YES
4: NO
5: NO
6: YES
7: YES
8: YES
9: YES
10: YES
11: YES
12: YES
13: YES
14: YES
16: YES
17: YES
18: YES
19: NO
20: YES
21: YES
22: YES
23: YES
24: NO
25: NO

Which is another combination.... so there are how many possible different combinations.... I figured it was 25 to the power of 2 which is 625, but then I thought actually it would be 2 to the power of 25 which is 33554432 so it must be that. As in you could write the list 33,554,432 different ways without repeating the same list twice.

Hey, that's exactly what I was about to write!!
