What are Dynamax Adventure Shiny Odds (SwSh)?

Question

I know if you catch all Pokémon it’s 1/100 with shiny charm and without charm it’s 1/300. Are the odds affected by how many of the Pokémon you catch during the adventure? (If you catch only the legendary, do you have lower shiny odds?)

Comments

all odds are 1/300 or 1/100. per pokemon. odds won't be impacted by how many pokemon you catch or don't catch, as each pokemon independantly has the 1/300 or 1/100 chance

That's not how it works.
Each individual Pokemon has a 1/100 chance to be shiny with the charm or a 1/300 chance with charm. The odds don't change with you catching or not catching Pokemon. Now I'm not probability expert so I'm not going to speak on how the probability changes with catching, but just know the odds themselves never change.

Answer 1

The shiny chances in Dynamax Adventures aren't based on how many Pokemon you catch. Every single one will have odds of 1/300 (without Shiny Charm) or 1/100 (with Shiny Charm).
