Answer:
See below.
Step-by-step explanation:
We are told that the probability of it raining tomorrow is 20%, and the probability of it not raining tomorrow is 80%.
20% represents 20/100 which simplifies to 1/5.
80% represents 80/100 which simplifies to 4/5.
If Philippe wants to make a spinner to simulate the probability of it raining tomorrow, he should create a spinner in the shape of a regular pentagon and divide it into 5 equal parts.
Label one part "Rain" to represent the 20% chance of rain.
Label the remaining 4 parts "Not Rain" to represent the 80% chance of it not raining.
This distribution ensures that the spinner accurately reflects the likelihood of rain and not rain, aligning with the given probabilities.
To simulate the probability of rain, Philippe should spin the spinner and let it come to rest naturally. If it lands on the "rain" section, Philippe considers this as a simulated instance of rain tomorrow. If it lands on one of the "not rain" sections, it represents a simulated instance of no rain tomorrow.
To get a more accurate representation, Philippe should repeat the spinning process multiple times. The more spins he performs, the closer the observed frequencies should get to the expected probabilities (20% for rain, 80% for not rain).
