• Each question can be answered yes or no, which means there are two possibilities for each question. Assuming the answer to each question is independent, which is reasonable to assume, then you compute:
  2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2.
  That is best shown as
  2^12
  which equals 4096.
