Jody and Todd's Messages — Decode the Season Code
Lesson 3 of 3
About this lesson
Jody replies to Todd's question in a unique-symbol code. The reply has six symbols, all different. Two seasons are eliminated because a known letter (T = Λ) doesn't match the code. A third is eliminated because Summer has two M's but the code has no repeated symbols. Only Spring survives.
