Answer:
I'm not exactly sure what this is asking, so i'm going to answer each part
A. 44%
B. 27%
C. 11.88% (assuming independence)
D. 61.36%
Step-by-step explanation:
Honestly I'm not really sure what he's asking but for A and B the answer is in the question. For C i assumed independence and multiplied the respective probabilities. For D I divided .27/.66 since it is a dependency probability
The probabilities of the events are
a. 0.44
b. 0.27
c. 0.1188
d. 0.2444.
What is probability?
Probability deals with the occurrence of a random event. The chance that a given event will occur. It is the measure of the likelihood of an event to occur.The value is expressed from zero to one.
For the given situation,
Statistics classes require a statistical calculator = 44% = 0.44
Statistics classes require a computer that has statistical software = 27% = 0.27
Of the classes that require a statistical calculator, classes also require the use of a computer = 15% = 0.15
a. P(Statistical Calculator) = 0.44
b. P(Statistical Software) = 0.27
c. P(Require a Statistical Calculator and Statistical Software) = [tex](0.44)(0.27)[/tex]
⇒ [tex]0.1188[/tex]
d. P(Require a Statistical Calculator GIVEN Require Statistical Software)
⇒ [tex]\frac{0.066}{0.27}[/tex]
⇒ [tex]0.244[/tex]
Hence we can conclude that the probabilities of the events are
a. 0.44
b. 0.27
c. 0.1188
d. 0.2444.
