What are the 4 types of causal relationships and how do they differ from each other?

The four types of causal relationships are deterministic, probabilistic, necessary, and sufficient. Deterministic relationships indicate that a cause will always lead to an effect. Probabilistic relationships suggest that a cause increases the likelihood of an effect happening. Necessary relationships mean that a cause must be present for an effect to occur. Sufficient relationships indicate that a cause alone can bring about an effect, but other factors may also contribute.
