Quantum Mechanics: Probablities

  1. Feb 18, 2015 #1
    Suppose we have a spin##-1## particle in a certain state ##|\phi\rangle## under the ##S_z## basis. How do you find the probabilities that a measurement of ##S_z## will result in the values of ##\hbar,0,## or ##-\hbar##?

    Also, what does it mean exactly when it says what is the probability that ##S_x## will result in the value of ##\hbar## in this state?

    Could it be that this question should be put to the homework section of these forums?
