First Time I'm Seeing Rewards Like These

I've been playing Splinterlands for almost three years now, since July 2019, and this is the first time I have gotten 2 packs in a single quest rewards. Super awesome and I think the other rewards don't even matter at this point.

I guess it might be more common in the diamond and champion leagues but what is the probability of a pack? Is it 1% so the probability of getting two packs is 1% * 1% which would be 0.01%. Of course, after all this excitement, there could be just rare and common cards in them.

Today was the second day in a row of the Earth quest. It was strangely a lot harder than yesterday with some tough opponents being matched up. Level 6 summoners will beat me every time because their cards gain so much more damage and abilities. Sometimes even level 4s will do that too.
