Rainy days The TV weatherman says, 鈥淭here鈥檚 a 30% chance of rain tomorrow.鈥� Explain what this statement means.

  • Use simulation to model chance behavior.

Short Answer

Expert verified

It will rain tomorrow.

Step by step solution

01

Step 1. Given Information

We need to clarify what the statement "there's a 30% chance of rain tomorrow" implies.

02

Step 2. Explanation

If the weather conditions are similar to today's, it is predicted that it will rain 30% of the time the next day. As a result, it will rain tomorrow on roughly 30% of days with identical weather conditions to today (or tomorrow's weather condition).
