Two fair coins are tossed. What is the probability that both show heads?
Answer and explanation
Correct answer: C. 1/4
- Step 1: List outcomes: HH, HT, TH, TT. Step 2. Only HH works, so 1/4. Answer: 1/4. Why not the others: 1/2 adds instead of multiplying; 1/3 counts unequal outcomes as equally likely; 2/4 counts HT and TH as both heads.
