Im pretty sure it's either Answer 1 or 2. Perhaps even both.
Shiny Charm can be very helpful.

No, I meant what is the chances with those

Oh k.
But im pretty sure that answer 1 and 2 have the highest chances.

That's insane.

Answer 1

You have a 1/4096 chance of finding a shiny. So for finding five shinies you would have to multiply 1/4096 by its self 5 times. So 1/4096^5. This overflows most calculators, but the awnser to your question is 1/1152921504606846976

This is the actual right answer. Do you guys even know probability?

Forgive my nitpicking, but I added in a few extra numbers for consistency.

Answer 2

Based on the responses on the internet and my own experience - since I have the shiny charm, it is highly unlikely, or even impossible to encounter a horde with all 5 being shiny.
Sweet scent just lures Pokemon faster and increases the encounters of hordes, but your chances still stay the same whether you use sweet scent of not. But, it might help since your increasing the probability of finding at least 1 shiny - not 5.

Hope I helped! :)

I think he was just asking out of curiosity. Even if it was probable, you can't even catch more than one horde Pokemon.
