A math quiz is made up of 5 multiple-choice questions, each with 4 possible answers. How many possible sets of answers are there?
Each question has 4 possibilities........so we have
4 possibilities for the first x 4 possibilities for the second x 4 possibilities for the third, etc.
So
4 x 4 x 4 x 4 x 4 = 45 = 1024 possibilities
