Not sure what that has to do with Pascal’s wager? This is just basic “expected value” in probability terms.
Plus wasn't it pascal who invented expected value?
And yes he was the inventor.
But logically, if any one God can exist, then so might any God or set of Gods from any pantheon, including sets never even conceived of by human beings. Since the evidence of any one God over another is the same (zero, it's entirely a matter of faith,) the benefit of belief in any one God over another is also zero, since the set of all possible Gods is infinite.
