immediate cause. --Samuel
Clark.

5. (Math.) Probability.
Note: The mathematical expression, of a chance is the ratio
of frequency with which an event happens in the long
run. If an event may happen in a ways and may fail in b
ways, and each of these a + b ways is equally likely,
the chance, or probability, that the event will happen
is measured by the fraction a/a + b, and the chance, or
probability, that it will fail is measured by b/a + b.
