Determine which of the following numbers could not represent the probability of an event. Explain your reasoning. (a). 33.3% (b)
1 answer:
Answer:
B and F
Step-by-step explanation:
The simple golden rule that we need to know here is
<em><u>"The probability of any event is always between 0 and 1 inclusive"</u></em>
<em><u /></em>
If an event has a probability of p(x), we can say:
Also, probability is ALWAYS POSITIVE.
Thus,
A) OK because 33.3% is 0.333, which is between 0 and 1
B) NOT OK, because probability isn't negative
C) 0.0002 is in between 0 and 1, so possible
D) 0 probability means it can't happen, so that's okay as well
E) this is a fraction with numerator less than denominator, which means its between 0 and 1, so OK
F) this fraction's numerator is greater than denominator, so it's greater than 1. Probability can't be greater than 1, so NOT OK
Out of these B and F cannot represent the probability of an event

Step-by-step explanation:
The equation of the line in slope-intercept form is:
Where m is the slope of the line and b is the y-intercept.
Then function given in the problem has the form:
Where:
m=3
b=-2
Therefore, it is a linear function.
By definition, the domain of the linear functions that are not bounded, is all the Real numbers.
Therefore, the answer is:
<em> {x | x is a real number}</em>
