A sure event is the one that contains the whole sample space.
An impossible event is the opposite case, when the event does not contain any element of the sample space.
Impossible Events:If the probability of occurrence of an event is 0, such an event is called as impossible event and if the probability of occurrence of an event is 1, such an event is called as sure event. In other words,the empty set ϕ is an impossible event and the sample space S is a sure event.
