How does this probability thing work in MWI?

I have read the Everett FAQ
(, and I think it's
one of the most comprehensive descriptions of MWI I have found on the
internet. I have one question though - in question 24: "Does many-worlds
allow free-will?", it says, "If both sides of a choice are selected in
different worlds why bother to spend time weighing the evidence before
selecting? The answer is that whilst all decisions are realised, some are
realised more often than others - or to put to more precisely each branch of
a decision has its own weighting or measure which enforces the usual laws of
quantum statistics.". My question is, where does this weighting come from?
Do some branches occur more often than others? Or is there just some sort
of assumed probability as to which world will be yours?
