A test has four questions: The first question is a true/false question, and it is followed by three multiple choice questions (answers a, b, c, d).

a. How many different ways can this test be answered if each question is answered?

1 answer

There are 2 ways to answer the true/false question (true or false), and 4 ways to answer each of the multiple choice questions (a, b, c, or d). Therefore, the total number of ways to answer the entire test is:

2 * 4 * 4 * 4 = 128

So there are 128 different ways to answer the test if each question is answered.
