What are the total outcomes when we throw three coins?

  • A.4
  • B.5
  • C.8
  • D.7

Answer: C

Each coin lands in one of two ways, and the three coins are independent, so the outcomes multiply.

\[ 2 \times 2 \times 2 = 2^{3} = 8 \]

Listing them: HHH, HHT, HTH, HTT, THH, THT, TTH, TTT. In general \( n \) coins give \( 2^{n} \) outcomes.
