    based on what you put there I also multiplied 4^2

    well you put 2^3 for the true or false which has 2 choices and 3 questions, therefore for the multiple choice which has 4 choices and 2 questions it should be 4^2

    ok same principle but it would be 2^4 not 4^2

    but 2^4 is the same as 4^2 they are both 16

    2^4 = 4^2

    2 is a factor of 4 but if you did not have example 3^2 is not = 2^3

    I assume that the T/F questions are all together on the test in one section and the same for the MC questions. And, I assume that the student answers every question - no blanks. For the 3 T/F questions there are 2 ways to answer each one. That gives 2*2*2 = 8 ways to answer the T/F questions. For the 2 MC questions, there are 4 ways to answer each one. That gives 4*4 = 16 ways to answer them. To answer the entire test with the T/F questions all together and the M/C questions all together, I get 2*2*2*4*4 = 128 ways to answer the test.

    Only if my answer is correct. Notice that I had to make those assumptions.

    true but you are 99% of the time correct so I have a high probability of it being the correct answer :)
