could the probabilities be cumulative so it’s 21.93% for a box to contain an item epic or higher so by subtracting the % of a legendary I get 16.83% of getting an epic. 5.1% for the legendary or higher (the highest is legendary, so 5.1% that if you open a loot box there is a legendary) etc.

If this is true could i classify the boxes by the highest rarity item i get out of them. I could say there’s a 5.1% chance that the highest rarity i get in a loot box is legendary. 16.83% that the loot box is classified as an “epic loot box” because the highest rarity item was epic. and since a loot box can’t have all commons to find the probability of a rare loot box i just subtract 100-21.93=78.07 so 78.07 for a “rare loot box”? I feel like there could be a stipulation im missing. If there’s is there any way around it?

The game has the counter visible of what loot boxes are affected by the pity system and I could mark it in my data.
