Thanks, I'm glad you like it. Hopefully enough people will complete it that it makes it out of beta!

I think your and is messing you up here. Looking at your logic, do the expressions on both sides of your and operator evaluate to true when it's sunny and the rain chance is < 0.5? In that case I think you want to be returning true but I don't think your logic matches that.

Perhaps a simpler way to think about it being sunny is to say "Take an umbrella if it's rainint OR if it's cloudy and looks like rain OR if it's sunny and the forecast is for rain."

Added example tests just now, thank you for the suggestion.
