What’s “universe” and what’s “experience”? What are you using probability of what for?
Supposing you assume some sense of expected utility maximization, what kinds of things have utility and probability? Also, for decision-making you need models of consequences of possible decisions, all of which except the actual one are not actually made, in particular models of probability have to be able to depend on your possible decisions. Focusing on “experience” doesn’t obviously give a way of addressing that.
