Answer

B and F could not represent the probability of an event.

Work Step by Step

B is incorrect because it is negative (-1.5). A probability of an event happening cannot be negative. If it is impossible then the probability must be 0. F is incorrect because 64/25 is greater than 1. The probability of an event happening cannot be greater than one. If it is certain, then the probability must be 1.
