EXHIBIT A
What you submitted
“An odds of 1 in 10^877 for an election result is equivalent to correctly calling roughly 2,914 fair coin flips in a row.”
TL;DR ·Mathematical principles support the equivalence, but provided sources do not mention these election odds.
WHAT WE FOUND
The claim asserts that a 1 in 10^877 probability is roughly equivalent to calling 2,914 consecutive fair coin flips. Statistical principles in the sources state that $n$ independent coin flips result in 2^n possible outcomes . Using this formula, 2^2,914 equals approximately 10^877.2, which confirms the comparison is mathematically sound and roughly equivalent . However, the provided sources regarding election modeling and accuracy do not mention any result or forecast featuring odds of 1 in 10^877 . While sources acknowledge that polling can be inaccurate due to sampling errors, they do not contain the specific figures cited in the claim . Consequently, the existence of an election result with these specific odds is UNVERIFIED .
