*You're making an implicit assumptionthat is usually harmless but _not_ when you're talking about the nature of quantum reality. You are forgetting that a Bernoulli trialis not a Bernoulli trialunless the Bernoulli trialhas been _OBSERVED_. And every observer observes that only two outcomes are possible, the coin lands heads or the coin lands tails. And after many trials all the observers in the Multiverse deduce that the outcome of one trial does not influence the outcome of another trial. And all the observers in the Multiversealso deduce that the probability of heads and the probability oftailsremains the same for every trial. And that is _exactly _what is required for something to be a Bernoulli trial.*
A Bernoulli trial does not require that the probability of heads and tails be equal.  But Everett entails that on every trial there will be an equal number of heads and tails across all worlds.
