How would you answer this problem

there are six holes that can either be opened or closed how many different combinations are there???v and the answer isn't 12

there are 2 choices for each hole, so

2 x 2 x 2 x 2 x 2 x 2 = 64 combinations <-------

36

6

is the answer 7.

well because you only get one option for each of them would't the answer be 6?
