Using Griffiths Quantum book (maybe ch 4?) but this problem is not from the book

2. Problem 2 1' A measurement of the z-romponent of the angular momentum is made on a particle in a state of total angular momentum 1 and x-component 1. What are the probabilities for obtaining the values 1, 0, and -1':' 2. For a particle in a slate of total angular momentum 1 and z-eulnponent l a measurement is made of the component of the angular momentum along an axis lying in the x-z plane and making an angle 9 with the z-axis. What is the probability of getting the values 1, 0, and -1
