Question

Fill in the blanks:

(i) Probability of a sure event is...........

(ii) Probability of an impossible event is...........

(iii) The probability of an event (other than sure and impossible event) lies between……

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

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

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

Answer 1

(i) 1, ∵ P(sure event) = 1

(ii) 0, ∵ P(impossible event) = 0

(iii) 0 & 1, ∵ O ∠ P(E) ∠ 1

(iv) Equal

(v) 1, ∵ P(E) + P(Bar E) = 1

(vi) 1
