Assistant: It looks like you're working on a text or exercise related to expressing certainty about a situation. Let me provide some guidance based on the sentences you've shared:

1. **You're 100% sure it is broken.**
   - "This computer must be broken."

2. **You're 50% sure it is broken.**
   - "This computer may/might/could be broken." 
   These modal verbs are used to express possibility, not certainty.

3. **You're 100% sure it is NOT broken.**
   - "This computer can't be broken." 
   "Can't" is used here to express strong disbelief or impossibility.

4. **"I don't believe your words! It cant x be true!"**
   - It seems like there's a typo with "cant x be true!" It should be "can't be true!" 

If there's anything more specific you need help with or if you're looking for additional exercises on modal verbs of certainty and possibility, feel free to ask!
