Math.

In here! Though that adds up the chances in all the giveaways you're entered in. :)

It depends.

1/X
X: number of entries for said giveaway

But yeah serious answer, the chance is equal for everyone joining a giveaway so the less people are participating the better the chances.

Depends if you have given cg a plate of cookies within the last 30 days.

Technically, the chance is 50%. Either you win or you don't :D

Normally its 10. But since last month's changes I think they increased it to 9. Anyway you should check the news feed since they explained it pretty well.

You either win or you don't.
