G Consider a system which is described by the state where A is a real constant (a) Calculate A so that OO is normalized. (b) Find L ?O?A? ?. (c) Calculate the expectation values of L x and L;2 in the state OO. (d) Find the probability associated with a measurement that gives zero for the z-component of the angular momentum. (e) Calculate N? L z OO and N? L ? OO where

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
