Question

the weather forecast for next season calls for a 10% chance of wind, a 20% chance of rain, a 30% chance of clouds, and a 40% chance of sunshine. if there are 90 days in the season, what is the predicted frequency for each type of weather? wind is predicted for days. rain is predicted for days. cloudiness is predicted for days. sunshine is predicted for days.

Explanation:

Step1: Calculate wind - predicted days

Multiply total days by wind probability: $90\times0.1 = 9$

Step2: Calculate rain - predicted days

Multiply total days by rain probability: $90\times0.2=18$

Step3: Calculate cloud - predicted days

Multiply total days by cloud probability: $90\times0.3 = 27$

Step4: Calculate sunshine - predicted days

Multiply total days by sunshine probability: $90\times0.4=36$

Answer:

Wind is predicted for 9 days.
Rain is predicted for 18 days.
Cloudiness is predicted for 27 days.
Sunshine is predicted for 36 days.
