Question
Which of the following is not a probability of the occurrence of an event?
(i) (ii) 0 (iii) (iv)
Solution
for probability of occurrence of any event A.
(i) lies between 0 and 1.
∴ It can be the probability of ocurrence of event A.
(i) lies between 0 and 1.
∴ It can be the probability of ocurrence of event A.
(ii) P(A) = 0 satisfies,
∴ It can be the probability of occurrence of event A.
(iii) does not lie between 0 and 1.
∴ It cannot be a probability of occurrence of event A.
(iv) does not lie between 0 and 1.
∴ It cannot be a probability of occurrence of event A.
∴ It can be the probability of occurrence of event A.
(iii) does not lie between 0 and 1.
∴ It cannot be a probability of occurrence of event A.
(iv) does not lie between 0 and 1.
∴ It cannot be a probability of occurrence of event A.
