Complete 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,spin the spinner 90 times to simulate the 90-day weather forecast. Which type of weather has the lowest observed frequency?
Answer:
Wind Weather
Step-by-step explanation
From the question above
The sample space(which means the total number of events that we are considering ) = 90 times of spinning which represents the 90 days weather forecast
The chance of wind weather occurring is 10% and its observed frequency of occurrence within the 90 days is = = 9 days
The chance of rain weather occurring is 20% and its observed frequency of occurrence within the 90 days is = = 18 days
The chance of cloud weather occurring is 30% and its observed frequency of occurrence within the 90 days is = = 27 days
The chance of sunshine weather occurring is 40% and its observed frequency of occurrence within the 90 days is = = 36 days
We see from the above calculation that the weather with the lowest observed frequency is Wind weather
