#6 {main}</pre> lies between 0 and 1.
∴ It can be the probability of ocurrence of event A.
(ii)     P(A) = 0 satisfies, 0 less or equal than straight P left parenthesis straight A right parenthesis less or equal than 1
∴ It can be the probability of occurrence of event A.
(iii)      straight P left parenthesis straight A right parenthesis equals negative 2 over 3 comma does not lie between 0 and 1.
∴ It cannot be a probability of occurrence of event A.
(iv)    straight P left parenthesis straight A right parenthesis space equals space 3 over 2 comma does not lie between 0 and 1.
∴ It cannot be a probability of occurrence of event A.
