Answer:
Our total number of options is thus 312=531,441
How does this altered question differ from the original? Well, it allows us the option of not answering anything, whereas, in the original, we had to answer at least one question.
So, to obtain the correct answer to the original question, we must remove the number of ways you can answer no questions. That’s easy, there is only one possibility, so the answer is simply 531,441 - 1 = 531,440
