(i) 0

The probability of an impossible event is zero because probability is likelihood of a given event's occurrence, which is expressed as a number between 0 and 1.

(ii) 1

The probability of a sure event is always 1 as the event may occur or may not occur and if its sure to occur there is only 1 probability for same.

(iii) 1

P(E) = 1/2 and P(not E) = 1/2 adding the two gives 1 because P(not E) is complement of event E.

(iv) 0, 1

The probability of a possible but not a sure event lies between 0 and 1 as an event is possible but not sure to occur. It may occur and may not occur.

(v) 1

The probability of the outcome of an experiment is one because an experiment may succeed or fail. P (E) + P(not E) = 1
