which of the following can be the probability of an event?

(a)-0.04 (b)1.004 (c)18/23 (d)8/7

Probability of an event (E) is always greater than or equal to 0. Also, it is always less than or equal to one. This implies that the probability of an event cannot be negative or greater than 1. So, in that case, option (c) is correct.
