How to get from the wavefunction to weighted states?

  1. Dec 8, 2015 #1
    I Have a question about how we arrive at the probabilities for the wavefunction collapsing to some specific value for an observable.

    As far as I'm aware, the wavefunction is a superposition of possible states depending on the observable we try to measure.
    Lets say I want to measure observable A,

    What is the procedure for getting from the wavefunction to a set of possible outcomes with coefficients that weight the possibilities?

    Apologies if the question isn't well formulated.
    thanks in advance.
