If we have probabilities for disjoint events:

$A, B, ..., \text{i.e.:}\space P(A), P(B), ..., \text{and}\space P(A) + P(B) + \ldots = 1$

then does this in fact mean, that there is a system, that has its activity (or in fact some abstract resources, that lead to the activity) partitioned between different tasks $A, B, \ldots$ ?

Seeing the probabilities as percentages of system's resources devoted to different tasks – is this a correct and useful approach, investigated in mathematics?

    If $A,B,\cdots$ etc are mutually exclusive events, then in what sense can a "system's resources" be distributed among them simultaneously? Unless you're into many-worlds interpretation type stuff.2012-05-08

    Your question is a little vague, to put it mildly.2012-05-08
