Answer:
1.) 33% days were cloudy
2.) Sunny days happened most often
Explanation:
1.) Go to the key to find which color is represented by "cloudy" which is orange. Then go to the pie to the orange slice and the percentage is there.
2.) The bigger slice of the pie is the weather that happened the most, so use the color to look at the key next to it: blue is the biggest slice and blue represents sunny.
