Question

What are the odds of finding 2 Spinda that have the same pattern and are shiny since the odds of finding 2 with the same pattern are 1 in 4 million?

Answer 1

I checked around, and Spinda has exactly 2^32 variations, or 4,294,967,296. You have a 1/8192 chance of having a shiny pokemon, so the probability of having just two is:
P(A)P(B)
1/2^321/8192=3.518 E13=chance of 1

so the chance of having two is
P(A)P(B)
3.518E131/8192=2.88 E17

-assuming my math is correct, you have a 1 in 288230376200000000 chance. Good luck with that.
It's about a .0000000000000001% chance by the way.

Does this mean that a shiny Spinda is more common than finding 2 Spindas that look the same. lol
