Let X() be a consistent probability assignment (function from statement to probability number).

What does it mean for this function to be "consistent"? What kinds of statements do you allow?

Let Y() be a probability assignment ...

What's X(Y is consistent)?

If "probability assignment" is a mapping from statements (or Goedel numbers) to the real interval [0,1], it's not a given that Y, being a "probability assignment", is definable, so that you can refer to it in the statement "Y is consistent" above.
