How many permutations are there for 6 questions, each with a yes or no answer choice?

Question

I am trying to create a survey with automated responses tailored to a respondent's unique choices, and need to make sure I cover every possible response!

Answer 1

There are six questions and every question has answer as YES/NO.

it means TWO choices for every question.

so answer will be 2⁶ that is 64 permutations.
