$$Question: A climate resilience planner is analyzing temperature data over 7 consecutive days and notes that each days temperature anomaly (deviation from average) is an integer between $-3$ and $3$, inclusive. What is the probability that the sum of all 7 daily anomalies is exactly zero?

**Understanding Climate Data Patterns in Extreme Weather Planning**
Why are planners and researchers increasingly focused on temperature anomalies across short timeframes? As public awareness of climate volatility grows, tracking daily deviations—especially over 7-day windows—helps anticipate heatwaves, cold snaps, and infrastructure strain. In cities across the U.S., understanding how small daily shifts accumulate remains critical for resilient community design and emergency response planning. This probability question centers on a climate resilience planner’s observation: over 7 consecutive days, each day’s temperature anomaly (deviation from long-term average) falls between $-3^\circ$ and $+3^\circ$, inclusive. The core inquiry: What is the chance the total anomaly sum over those days adds precisely to zero? Though simple in concept, the math reveals nuanced patterns with practical implications. ## Why This Question Reflects a Growing Trend in Climate Preparedness Public discourse increasingly connects short-term weather variability to long-term climate shifts. With rising frequency of extreme temperature fluctuations, planners turn to statistical modeling for risk assessment. The anomaly-based approach enables precise, localized analysis—essential for developing adaptive strategies. Platforms promoting climate literacy now emphasize probabilistic thinking, helping audiences grasp when random daily swings align into measurable trends or risks.
