Can the experimental probability of an event be a negative number? If not,why?
(B) No,the experimental probability of an event cannot be a negative number.
Probability is defined as the ratio of the number of trials in which the event occurred to the total number of trials.
Since both the number of trials in which the event occurred and the total number of trials are non-negative integers (and the total number of trials is always greater than $0$),the resulting ratio must be greater than or equal to $0$.
