Question

Determine which numbers could not be used to represent the probability of an event. A. 0.0002, because probability values must be rounded to two decimal places. B. 33.3%, this is because probability values cannot be greater than 1. C. 0, because probability values must be greater than 0. D. 64/25, because probability values cannot be greater than 1. E. 320/1058 because probability values cannot be in fraction form 1058 F. -1.5, because probability values cannot be less than 0.

Answer 1

The values 64/25 and -1.5 could not represent probabilities as they violate the rules that probabilities must be between 0 and 1, with D being greater than 1 and F being negative. Option D and D are correct.

Step-by-step explanation:

The numbers that could not be used to represent the probability of an event are the ones that do not meet the basic probability rules.

Specifically, option D (64/25) and option F (-1.5) are incorrect because probability values cannot be greater than 1 and cannot be less than 0, respectively.

Option A (0.0002) can represent a probability as it is between 0 and 1, and probabilities do not have to be rounded to two decimal places.

Option B (33.3%) is valid as it is less than 100% (or 1 when expressed as a fraction).

Option C (0) is valid because a probability value can be 0, indicating that an event is impossible.

Lastly, option E (320/1058) is a valid probability in fraction form and does not violate any probability properties.
