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.

Hey!!

here is your answer >>>

As we know, The formula for the length of a trinagle is

(1/2)(base)(height) !.

Height is 6/5 and area is 2/5, then what is the base, we will just have to substitute these values!.

which is ,

2/5 = (1/2)(base)(6/5)

2/5 = (base)(3/5)

base = (2/5)/(3/5)

base = (2/5)(5/3)

base = 2/3 ft!.

Hope my answer helps!
