well, I have solution but I don't understand it. It would be helpful if someone explained me the solution.
Here it is :

This question tests the fundamental counting principle, which states that the total number of choices is equal
to the product of the independent choices. The five separate test questions give you five independent choices. For the
three multiple choice questions there are four options each, whereas for the two true/false questions there are two
options each. Multiplying the independent choices yields (4)(4)(4)(2)(2) = 256 different ways to answer the exam.
