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 days

Multiply total days by wind percentage:
$90 \times 10\% = 90 \times 0.10 = 9$

Step2: Calculate rain days

Multiply total days by rain percentage:
$90 \times 20\% = 90 \times 0.20 = 18$

Step3: Calculate cloud days

Multiply total days by cloud percentage:
$90 \times 30\% = 90 \times 0.30 = 27$

Step4: Calculate sunshine days

Multiply total days by sunshine percentage:
$90 \times 40\% = 90 \times 0.40 = 36$

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.
