word usage - Is this a clear expression, "on a rainy day, Bob is grumpy with a 60 % chance, happy with 40 %"?

This question comes from this post, where I am trying to express the following meaning clearly and concisely.

this is clear but not concise

on a rainy day, Bob is grumpy with a 60 % chance, Bob is happy with a 40 % chance.

is this clear and concise?

on a rainy day, Bob is grumpy with a 60 % chance, happy with 40 %

Answer

Thank you for linking to the post where the statement originated. It explains the very odd, and perfectly correct, syntax of (thing occurs) with a (percent) chance.

The most concise you should make the sentence, and still have it readable for humans, is something like :

On a rainy day, Bob is grumpy with a 60 % chance and happy with a 40 % chance.
