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
This question is incomplete because it lacks the appropriate figure. Find attached to this answer the diagram of the figure.
Answer:
8%
Step-by-step explanation:
The formula for Probability =
Numbers of possible outcomes ÷ Number of events.
From the diagram, Number of Possible outcomes is given as = Number of Adults that prefer auto racing = 179 adults
Number of events is obtained from the questions as the Number of Adults = 2237 adults
Probability that an adult chosen at random prefers auto racing = 179 adults /2237 adults
= 0.0800178811
Rounding my answer to the nearest whole percent, the probability that an adult chosen at random prefers auto racing
= 0.0800178811 × 100
= 8%
