Explain a fraud filter's precision and recall in three numbered lines

About this exercise

Your fraud review manager asks how well the new filter works. Write exactly 3 numbered lines with the math shown: 1 how many of the flagged orders were truly fraud (precision), 2 how many of the real fraud orders were caught (recall), 3 what each means for the review team's workload in plain words. Plain text, under 90 words, percents to one decimal.

Common mistakes when you ask AI for this

• Mixing up the denominators. The AI divides by all orders (1,000) instead of flagged or fraud totals. Try: Add: "Precision = 40 / 100 flagged; recall = 40 / 50 truly fraud."
• Jargon for the manager. The AI explains false positives and negatives. Try: Add: "Line 3 in plain words: 60 of 100 reviews wasted; 10 of 50 fraud orders slip through."
• Skipping the working. The AI gives percents only. Try: Add: "Write each division with the numbers."
• Leaving the format to chance. The AI picks its own length and layout unless told the exact shape. Try: Add: "Exactly 3 numbered lines. Plain text, no bold or headings."
• Trusting the AI to count words. AI is bad at counting. Ask for a total word limit and it often lands over it. Try: Cap each part instead, for example "each line under 15 words."
