Question

The weather forecast for next season calls for a 10% chance of wind with no rain or clouds, a 20% chance of rain with no wind, a 30% chance of clouds with no wind or rain, and a 40% chance of only sunshine. Describe a 10-section spinner that could be used to model this situation. Which forecast is most likely?

Answer 1

To create a 10-section spinner that models the weather forecast, we can allocate the sections according to the probabilities of each weather condition provided.

1. **Chance of Wind (10%)**:
- This translates to 1 section (10% of 10 sections = 1 section).

2. **Chance of Rain (20%)**:
- This translates to 2 sections (20% of 10 sections = 2 sections).

3. **Chance of Clouds (30%)**:
- This translates to 3 sections (30% of 10 sections = 3 sections).

4. **Chance of Sunshine (40%)**:
- This translates to 4 sections (40% of 10 sections = 4 sections).

Now, we can break down the spinner into the following sections:

- 1 section for Wind
- 2 sections for Rain
- 3 sections for Clouds
- 4 sections for Sunshine

Here’s how you might label each section:

- **Section 1:** Wind
- **Sections 2-3:** Rain
- **Sections 4-6:** Clouds
- **Sections 7-10:** Sunshine

This spinner effectively represents the weather probabilities.

**Most Likely Forecast:**
Based on the sections of the spinner, the weather condition that is most likely to occur is Sunshine, as it has the most sections (4 out of 10) representing 40% of the total Spinner.
