AFour outcomes
BTwo outcomes
CThree outcomes
DEight outcomes
Answer & Solution
Correct answer: A. Four outcomes
1. Each toss can land two ways, heads or tails.
2. The second toss doubles each of those, giving two times two.
3. That is four outcomes: HH, HT, TH and TT.
4. HT and TH are counted separately because the order of the two tosses differs.
