What are the odds of getting 2 Masuda Method shinies with HA, same nature, and same gender?

Oct. 14, 2022

I recently got 2 shiny lapras from the same egg pile. Both are hidden ability (Hydration), Male, and have the Brave nature. What are the odds of that?

Masuda method odds in gen 8 and with the shiny charm are 1/512

The odds of getting a specific nature is 1/25

Lapras’ gender ratio is 50% 50%

And the odds of getting a hidden ability from eggs if the mother has it is 60%

If someone could tell me the odds of that, that would be appreciated

Edit: Also iirc they were hatched 29 eggs apart from each other

Normal Masuda Method shiny odds: 1/512 or 0.1953125%

I don’t really want to do these calculations myself because I know they don’t make up a perfect model for Pokemon’s RNG…

This number isn’t exactly right because of Pokemon’s complicated RNG, but it paints a pretty close picture as to how rare this occurrence is.
