Are the historical events which have occurred extremely unlikely and what history has a higher probability of occurring?

Historical events which have occurred have a probability of 1. They are a certainty. This refers to the event itself, not some historian's or politician's interpretation of what happened. However, the probability that they will occur again depends on the event. Exact recurrence is impossible (probability = 0).

Which value shows a greater probability that the result did not occur by chance 0.05 or 0.001?

In the context of significance tests, the value of 0.001 indicates a lesser likelihood that the event occurred by chance, that is a greater probability that it did not occur by chance.In the context of significance tests, the value of 0.001 indicates a lesser likelihood that the event occurred by chance, that is a greater probability that it did not occur by chance.In the context of significance tests, the value of 0.001 indicates a lesser likelihood that the event occurred by chance, that is a greater probability that it did not occur by chance.In the context of significance tests, the value of 0.001 indicates a lesser likelihood that the event occurred by chance, that is a greater probability that it did not occur by chance.
