  The Kochen-Specker theorem states that exclusive and complete deterministic
outcome assignments are impossible for certain sets of measurements, called
Kochen-Specker (KS) sets. A straightforward consequence is that KS sets do not
have joint probability distributions because no set of joint outcomes over such
a distribution can be constructed. However, we show it is possible to construct
a joint quasiprobability distribution over any KS set by relaxing the
completeness assumption. Interestingly, completeness is still observable at the
level of measurable marginal probability distributions. This suggests the
observable completeness might not be a fundamental feature, but a secondary
property.
