Five coins are placed on a table in a straight line: A, B, C, D, and E. Exactly two coins show heads. Coin A and Coin E show the same face. Coin B and Coin D show different faces. Coin C shows tails. If Coin A shows heads, which two coins show heads?
Coin A and Coin E
Coin A shows heads, and since Coin E shows the same face as Coin A, Coin E must also show heads. Because there are exactly two coins showing heads in total, all remaining coins (B, C, and D) must show tails.
