Here is an energy basis state of three electrons in a magnetic field?

Are all three of these electrons entangled? What is the probability that a measurement of the first electron?s spin yields +1/2 ?? If the first electron?s spin is measured to be +1/2 ?, what would a measurement of the second and third electrons spins yield? Does this result change if the first electron?s spin is measured to be -1/2 ??
