Identify sample space outcome using designations


A student takes a pop quiz that consists of three true-false questions. Each question can be answered correctly (C) or incorrectly (I). Consider this to be a three-step process; i.e., answering the first question with a C or an I, answering the second question with a C or an I, and answering the third with a C or an I.

a) Identify each sample space outcome using the C and I designations.
b) What is the probability that the student gets all three questions correct?
c) What is the probability that the student gets exactly two questions correct?
