quantum mechanics - EPR Paradox resolution: the spin is fixed at creation but its measurement isn't?


The Wikipedia article on the EPR paradox uses the example of an electron and positron created from a common source, each moving in an opposite direction to the other. Detector A is used to measure the spin of the electron, B measuring the spin of the positron.


The whole article gives the impression of something "paradoxical" being involved whereas I don't and so perhaps I'm misinterpreting the paradox:


At the instant of creation, the electron and positron have opposite but definite spins along an axis, but we can only use probabilities when predicting the outcome of measuring it?
