And for many worlds. Doesn't it punt randomness into other universes, but doesn't help us solve for results in our own individual universe. Since we can't measure what happens in the other universe we don't really know. If there were two results, and one is in one universe, and one in our universe, sure we determinedly know both results. But we don't know which universe we are in, so instead of a random result, now we have 2 answers and 2 universes, but now randomly don't know where we are?
