At a college, 72% of courses have final exams and 46% of courses require research papers. Suppose that 32% of courses have a res
Ghella [55]

Answer:

a) P(F UR) = P(F) +P(R) -P(F and R) = 0.72+0.46-0.32=0.86

b) P(FUR)' = 1-P(FUR)= 1-0.86 = 0.14

Step-by-step explanation:

Let's define the following events first:

F: The event that a course has a final exam.

R: The event that a course requires a research paper

From the info provided we have that:

P(F) = 0.72, P(R) =0.46 P(F and R) =0.32

So then we can create a Venn diagram as we can see on the figure attached.

a. Find the probability that a course has a final exam or a research project.

For this case we can find the probability like this:

P(F UR) = P(F) +P(R) -P(F and R) = 0.72+0.46-0.32=0.86

b. Find the probability that a course has NEITHER of these two requirements.

For this case we can use the complement rule and we can find the probability like this:

P(FUR)' = 1-P(FUR)= 1-0.86 = 0.14

And that's the same value obtained with the diagram.

Analia wants to know which school has higher athletic achievement relative to the budget per student
user100 [1]

Answer:

SAT average divided by budget per student

Graduation rate divided by budget per student

No. The definitions have opposite results.

Step-by-step explanation:

DID IT ON KHAN and

The key understanding here is that there isn't a single way to define "academic achievement." Graduation rate can be a good measure of that. Average SAT is also a good measure. The rate of students who are accepted into college can also be a good measure, but we are not given information about that.

Now let's go over the options and see which of them might be used to describe "academic achievements relative to the budget per student."

Hint #22 / 4

Definition Analysis Appropriate?

SAT average divided by budget per student "SAT average" is a measure of academic achievement. Dividing this by the budget per student gives us a good definition.

Yes

Graduation rate divided by budget per student "Graduation rate" is a measure of academic achievement. Dividing this by the budget per student gives us a good definition.

Yes

Yesstart color #1fab54, start text, Y, e, s, end text, end color #1fab54

Number of sports medals won divided by budget per student "Number of sports medals won" isn't a measure of academic achievement.

No

Nostart color #e84d39, start text, N, o, end text, end color #e84d39

Graduation rate divided by number of sports medals won "Graduation rate" is a measure of academic achievement, but it's divided by the number of sports medals won, and not by the budget per student.

No

Nostart color #e84d39, start text, N, o, end text, end color #e84d39

Hint #33 / 4

We are left with two definitions for academic achievements relative to the budget per student:

SAT average divided by budget per student

Graduation rate divided by budget per student

Let's calculate the academic achievements relative to the budget per student for each school according to each definition:
