What is a proof?

[Muslim Scholar]

and prove to you that your deduction is faulty and Billy is indeed a black swan. Then you must change your assumptions to:

a) Swans are either black or white.
b) Billy is a swan.
c) Therefore Billy is black or white.

You are correct
This proof fails because its premises is false (or not accurate)

1:It is weak because it relies on probability, deductive does not.
and i just said that

I only disagree with the word "weak"
you should change it to probable because a probability of 0.001 is not equal to another of 0.999
