Impossible: It is an event which is certain not to happen is called impossible events. The probability of the event is $0$ . Example: Choosing a blue ball from a basket of red balls is an impossible event.

Even chance: If there is chance of one event to occur in between two events is called even chance. The probability of the event is $\frac{1}{2}$ . Example: If we throw a coin, the probability to get head is $\frac{1}{2}$ .
