Answer:

The answer to your question is "it is necessary to order 85 pizzas to feed 300 students"

Step-by-step explanation:

Data

7 pizzas feed 25 students

? pizzas feed 300 students

To solve this problem use proportions

We know:

                          7 pizzas ------------------   25 students

                           x pizzas -----------------   300 students

Solve using cross multiplication

                           x = (300 x 7) / 25

Simplification

                           x = 2100 / 25

Result

                           x = 85 pizzas

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.
