If I hatch 512 pokemon with shiny charm and masuda method what

It doesn't work like that. Each individual one has a 1/512 chance of being shiny

>>31168088
Pretty much what >>31168124 said.

Odds aren't the same as percentages.

1 in 512

Mathematically speaking, you have roughly a 63% chance for one of those 512 mons to be shiny.

>>31168213
this is correct

Can someone explain the math behind this? I'm rusty with probability.

roughly 63% chance for one OR MORE to be shiny*

>>31168213
Elaborate.

>>31168319

chance for none to be shiny out of one = 511/512
chance for none to be shiny out of two = (511/512)^2
and so on
chance for none to be shiny out of 512=
(511/512)^512=about 0.37
chance for one or more to be shiny out of 512=1-0.37-0.63

Actually it is 1:3: normal, shiny or cooked.

It only took me <100 eggs with no charms.
