Answer 2

1 ; 0 ; 0 and 1 ; equal ; 1 ; 1.

Step-by-step explanation:

(i) Probability of a sure event is 1.

(ii) Probability of an impossible event is 0.

(iii) The probability of an event (other than sure and impossible event) lies between 0 and 1.

(iv) Every elementary event associated to a random experiment has equal Probability.

(v) Probability of an event A+ Probability of event ‘not A’ = 1.

(vi) Sum of the probabilities of each outcome in an experiment is 1.
