Answer: ..
Explanation:
Wed: 0%
Thu: 30%
Fri: 50%
Sat: 80%
Sun: 100%
I got these answers by taking 100, and subtracting the rain percentage from it. For instance, if it was a 45% to rain, and a unknown amount for it to not rain, I would take 100 and subtract 45 from it, resulting in a 55% chance of it not raining.
