How this calculation works
Any part of the event interval outside the distribution support contributes zero probability.
THE FORMULA
P = length(event ∩ support)/length(support)A worked example
The interval 2 to 5 has length 3 out of a uniform support length of 10.
Good to know
A single exact value has probability zero.
