Course: Introduction to Game Theory

Two fair coins are flipped. What is the probability of getting at least one heads?

✅ Correct! The correct answer is:

3/4

Explanation:

The sample space is {HH, HT, TH, TT}. Three of these four outcomes contain at least one heads, so P = 3/4. Alternatively, P(at least one H) = 1 - P(no H) = 1 - 1/4 = 3/4
