That's not right. You're setting your expectation for N = 100m miles, then updating it for N = 3 million miles?

That's like saying: "I rolled this red d20 twenty times before I rolled a 1, whereas I rolled a 1 the first time on this blue d20, so the red d20 is obviously better and I'm rolling all my saves on it".

Or, I don't know- "I rolled three 1s on this d20 in twenty rolls so it's obviously not a fair d20".

Can you clarify? What do you believe to be wrong and why?

If you have a strong prior the dice are equivalent, then yes, the rolls shouldn't change your mind.

If you have a prior that the dice are weighted in an unknown way, then yes, the rolls really should change your mind.
