, is defined since the occasion price at time t conditional on survival right until time t or afterwards (that is, T ≥ t). Suppose that an merchandise has survived for just a resource time t and we wish the chance that it's going to not endure for an extra time dt:

Now all commands need to terminate which has a semi-colon. To return to employing carriage return as the delimiter use
