A student chooses only one course from (6) online courses or (3) offline courses. How many total choices are there?

Answer and explanation

Correct answer: 9

The student must choose only one course, either online or offline. These are mutually exclusive choices, so apply the addition rule: \(6+3=9\). Hence, there are 9 possible choices. \(18\) would result if one online course and one offline course had to be chosen together; that would use the multiplication rule. Exam tip: For “or” with exactly one choice, usually add the numbers of alternatives.
