解説 (JP): 根拠や情報に基づいて、高い確率でそうだろうと推測する時に使います。客観的な状況や常識から考えて、当然そうなるはずだという確信を表します。\n\nCommon Mistakes:\n❌ わけがない: This is a strong denial meaning 'there is no way'. It's a bit contradictory to say 'there is no way he's here' when his bag is right there on the desk!\n❌ べきだ: This expresses an obligation (should/must). Let's deduce his location like a detective using 'に違いない' (must be) based on the clue of his bag, instead of giving him an obligation!\n❌ のはずだ: The meaning is perfect! But there's a strict Japanese rule: verbs (いる) connect directly to 'はずだ' without 'の'. If it were just 'いるはずだ', you would be totally right!
