WebSub-probability measure. In the mathematical theory of probability and measure, a sub-probability measure is a measure that is closely related to probability measures. While probability measures always assign the value 1 to the underlying set, sub-probability measures assign a value lesser than or equal to 1 to the underlying set. WebThe following theorem tells us that a function of bounded variation is right or left continuous at a point if and only if its variation is respectively right or left continuous at the point.5 Theorem 9. Let f∈BV[a,b] and let vbe the variation of f. For x∈[a,b], f is right (respectively left) continuous at xif and only if vis right (respectively
