1. The problem statement, all variables and given/known data If electron (1) is in a state described by cosα1χ+ + sinα1e iβ1 χ- and electron (2) is in a state described by cosα2χ+ + sinα2e iβ2 χ-, what is the probability that the two-electron state is in a triplet state? 3. The attempt at a solution I already solved this problem; I have a conceptual question about solving it using a relation that would make my solution a lot simpler. I read somewhere online that the probability of finding the electron system in the triplet state can be equated to (1 - the probability of finding the electron system in the singlet state). I was wondering how this is possible. Thanks for any input.
