2 questions in the course bank use Sample space, in Probability of Simple Events, Probability of Compound Events.
Problem 1
Two fair coins are flipped. Find P(exactly one head).
Worked answer
1/2
Sample space: HH, HT, TH, TT — four equally likely outcomes
Exactly one head: HT and TH, so two of them
24 = 12 — not 13, because "one of each" happens two ways.
Problem 2
Two fair dice are rolled. How many outcomes are in the sample space?
Worked answer
36
6 × 6 = 36
