Solomonoff induction combined with an unbounded utility function gives undefined expectations. But Solomonoff induction combined with a bounded utility function can give defined expectations.

Yes.

And Solomonoff induction by itself gives defined predictions.

If you try to use it to estimate the expectation of any unbounded variable, you get an undefined value.

Probability is a bounded variable.

Yes, but I'm not sure I understand this comment. Why would you want to compute an expectation of a probability?
