About this exercise
You're giving the CFO a probability-weighted revenue view. Write a prompt for plain text with lines starting "Low:", "Base:", "High:", "Probability check:" and "Expected value:". Scenario lines show probability x revenue. The check line adds the probabilities and says whether they total 100%. Use the corrected Low probability. No advice and no view on which case is likeliest. Under 80 words. No bullets or numbering.
Common mistakes when you ask AI for this
- Using the draft 30%. The AI uses 30% for Low and the check shows 105%. Try: Say: "Use the corrected Low probability of 25%."
- Commenting on likelihood. The AI says Base is the likeliest case. Try: Add: "No comment on which case is likeliest."
- Missing the check. The AI skips the probability check. Try: Add: "Probability check: add the three and say whether they total 100%."
- Markdown extras. The AI adds bold labels, headings and a closing note. Try: Say: "Plain text, no bold. Output only the lines asked for."
- Trusting the AI to count words. AI is bad at counting and runs past word limits. Try: Ask for fewer words than the real cap and keep each line short.
What a strong prompt includes
- Names the five lines
- Uses the correction
- Asks for the check
- Bans advice
- Caps length
