Diglett17.6%
Geodude16.6%
Grimer12.8%
Meowth20.3%
Sandshrew18.1%
Vulpix14.5%

We think that the odds of getting each type of Alolan Pokemon are 16.6% as there is only a slight deviation in each Pokemon.

The chance to hatch a regional is 12.5%

Pokemon% of Regional Eggs
Tauros28.3%
Farfetch’d21.0%
Mr. Mime25.1%
Kangaskhan25.7%

We can see from this that they are all roughly around 25%, and we have no reason to believe Niantic would boost certain ones over others.

The chance to hatch a Tangela or Porygon is 12.5%

The odds of Getting Tangela or Porygon is in ratio 1:1
