A weather model predicts a 40% chance of rain on Monday, a 50% chance on Tuesday, and a 60% chance on Wednesday. Assuming independence, what is the probability that it rains on all three days?

**A weather model predicts a 40% chance of rain on Monday, a 50% chance on Tuesday, and a 60% chance on Wednesday. Assuming independence, what is the probability that it rains on all three days?** In an era where precise forecasts shape daily decisions—from commutes to weekend plans—this weather model has sparked quiet interest across the US. With increasing reliance on data-driven planning, users are asking: what do these probabilities really mean when stacked across consecutive days? Understanding how weather models estimate rainfall across independent days offers insight not only into atmospheric science but into how people manage risk and schedule their lives. **Why This Rain Forecast Pattern Is Capturing Attention** Across U.S. cities, the convergence of these specific daily probabilities—40%, 50%, and 60%—draws curiosity because consumers increasingly value granular, probabilistic forecasts. Unlike vague “chance of rain” statements, this model delivers transparent, percent-based estimates that align with decision-making frameworks used in weather-sensitive industries like transportation, agriculture, and event planning. The rising frequency of real-time updates from advanced weather models amplifies public awareness, fueling conversations about preparedness and variability in short-term climate shifts.
