There would be 2^11 possible answers or 2048.
(2)50 = 1,125,899,906,842,624 possible different sets of answers for the entire test.
The number of possible outcomes would be 2^6 = 64, since each of the six questions have two possible outcomes.
If there are 5 questions, each with 2 possible answers, there will be 25 different quiz outcomes possible. We know that 25 = 32 different possible outcomes on a competed quiz where one answer is selected for each question.
