Question

You are going to take a 10-question True/False test. How many ways can this test be answered if leaving questions blank is a viable option for each question?

Answer 1

59049 ways

Explanation:

We are told one could answer true, false or have the option of leaving the question blank.

Now, for each question, it means that there are 3 ways to answer it.

Thus for 10 questions, total number of ways to answer will be; 3^(10) = 59049 ways
