Strategies can be developed to reduce either the probability of an event or the consequences, or both (Dai et al. 2002; Brooks 2003; Sarewitz et al. 2003).
Expert writing Tips
Best practice
When using the term "probability", ensure it's clear whether you are referring to one of several probabilities in a set. Using "either of the probabilities" or specifying the event or case the probability refers to improves clarity.
Common error
Avoid using "either probability" without specifying which probability you are referring to. This can lead to confusion. Instead, specify "either probability of success" or "either probability in this model".

Ludwig's WRAP-UP
In summary, the phrase "either probability" is not considered grammatically correct in standard English without additional context. Ludwig flags it as a phrase that lacks clarity, needing further definition. While found in science and news sources, its ambiguity makes it less effective for formal or precise communication. For clearer and more effective writing, it is recommended to use alternatives like "either of the probabilities", "probability of either event", or providing further context to specify which probability is being referenced. This ensures that the intended meaning is accurately conveyed and avoids potential confusion.

FAQs
What does "either probability" mean?
The phrase "either probability" is not standard English. It likely intends to refer to one of two probabilities, but requires more context to be clear. It's better to use "either of the probabilities" or specify the event the probability refers to.
How to use "either probability" in a sentence correctly?
While not grammatically ideal, the phrase can be used if properly contextualized. For example: "In this experiment, we can consider "probability of success" or "probability of failure", and assess either probability in relation to the outcome."
Is it better to say "either probability" or "either of the probabilities"?
"Either of the probabilities" is grammatically more correct. "Either probability" alone sounds incomplete and requires more context to be fully understood.
What can I say instead of "either probability"?
Consider alternatives like "probability of either event", "probability in either case", or specifying the events or outcomes associated with each probability.
