The probabilistic account of causation is presented in this chapter. Roughly, this account states that causes increase the probability of their effects. As a notorious problem for such a simple characterisation of causation, the case of spurious causation will be explained. This permits introducing the notion of screening off, which is crucial to the discussion of overdetermination cases. In general, redundant causes screen other causes off from their effects. Again, a notion of causation with regard to some context will be illuminating with respect to overdetermination scenarios.
