Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:
In an office building, there are five floors. A company CEO announces that he has hidden a bonus check for one lucky employee somewhere in the building. He mentions that the check is not on the first floor. During lunchtime, two employees overhear a conversation between the CEO and his assistant, revealing that the check is also not on the second or third floors. These employees decide not to share this information with their colleagues. What do the employees who only heard the initial announcement think about the location of the bonus check, and what do those who overheard the conversation think? Respond very briefly.

### Response:

The employees who only heard the initial announcement from the CEO think that the bonus check could be on the second, third, fourth, or fifth floors because the CEO only mentioned that it is not on the first floor. They would likely consider that they have a one in four chance of finding the check if they searched those floors. 

On the other hand, the employees who overheard the CEO's conversation with his assistant know that the check is not on the first, second, or third floors. Therefore, they understand that the check must be on either the fourth or fifth floor, and they only have two floors to search. This information gives them a better chance of finding the check since they can focus their search on fewer floors.
