Question

Determine which numbers could not be used to represent the probability of an event. select all that apply.

Answer 1

The answer to this question would be: 
a. minus− 1.5, because probability values cannot be less than 0.
c. startfraction 64 over 25 endfraction 64 25 , because probability values cannot be greater than 1.

Probability would be in a range of 0-1. There won't be minus probability since the lowest possible will be 0. If the number using percent like 33.3%, then the maximal probability is 100%. If you calculate 64/25 you will got 2.56 which was higher than 1.

Answer 2

Probability of an event is always greater than or equal to 0 & less than or equal to 1,

So, the range of probability is [0, 1]

Here,
a. minus−​1.5, because probability values cannot be less than 0. CORRECT
b. ​0.0002, because probability values must be rounded to two decimal places. WRONG 0.0002 is greater than 0 & less than 1
c. startfraction 64 over 25 endfraction 64 25​, because probability values cannot be greater than 1. CORRECT
d. ​33.3%, this is because probability values cannot be greater than 1. WRONG 33.3 % is less than 1 & greater than 0.
e. startfraction 320 over 1058 endfraction 320 1058​, because probability values cannot be in fraction form. f. ​0, because probability values must be greater than 0.WRONG 33.3 % Probability values can be written in fraction, But it's decimal value of fraction should be greater than 0 & less than 1.
