Detailed Solution

Let us check the options for finding the possible probability of an event.
(3) correct answer: Probability of an event always lies between 0 and 1. Thus, the possible value of the probability of an event is given by 0.3
(1) incorrect answer: The probability cannot be greater than 1. Thus, (1) is not the correct option
(2) incorrect answer: Probability must be greater than or equal to 0 and less than 1 and hence, cannot be equal to -1 . Thus, (2) is not the correct option.
(4) incorrect answer: The probability of an event must be greater than or equal to 0 and less than or equal to 1. Thus, probability cannot be equal to 112. Hence, (4) is the incorrect option.
So, the possible value of the probability of an event is equal to 0.3.
Hence correct option is 3.
