Answer 2

Given Information:

- Number of rainy days: 15 - Number of windy days: 10 - Number of cold days: 6 - Number of rainy and windy days: 3 - Number of windy and cold days: 2 - Number of rainy and cold days: 4 - Number of rainy, windy, and cold days: 2

Calculation:

To find the number of unfavorable days, we need to add the number of rainy days, windy days, and cold days, and then subtract the days that have overlapping weather conditions (rainy and windy, windy and cold, rainy and cold), and finally add back the days that have all three weather conditions (rainy, windy, and cold).

Let's calculate step by step:

1. Number of unfavorable days = Number of rainy days + Number of windy days + Number of cold days - Number of unfavorable days = 15 + 10 + 6 = 31

2. Subtract the days that have overlapping weather conditions: - Subtract the number of rainy and windy days: 31 - 3 = 28 - Subtract the number of windy and cold days: 28 - 2 = 26 - Subtract the number of rainy and cold days: 26 - 4 = 22

3. Add back the days that have all three weather conditions: - Add the number of rainy, windy, and cold days: 22 + 2 = 24

Therefore, the number of unfavorable days is 24.

Conclusion:

The number of unfavorable days, considering rainy, windy, and cold weather conditions, is 24.
