A survey is conducted at a college with students, faculty members, and administrators. Each of these individuals has a single email address listed in the online campus directory. Suppose one email address was selected at random. What is the probability it would be (a) a student, (b) a faculty member, (c) an administrator, (d) a faculty member or administrator, and (e) anyone except an administrator? (f) Explain your answers to someone who has never had a course in statistics.

Incomplete question. First, we need to know the number (population) of persons in the survey. Let's assume;

Total population = 1,000 individuals

Explanation:

a) To find the probability it would be a student, we divide the number of college students by the total population= 800/1000 = 0.8%

(b)To find the probability it would be a faculty member, we divide the number of faculty members by the total population= 50/1000= 0.05%

(c) To find the probability it would be an administrative staff, we divide the number of administrative staffs by the total population= 150/1000 = 0.15%

(d) To find the probability it would be a faculty member or administrator, we add the number of faculty members with the number of administrative staffs  and then divide by the total population=  (50+150)/1000= 0.2%

(e) To find the probability it would be anyone except an administrator, we subtract the number of administrative staffs from the total population  and then divide by the total population=  1000-150= 850/1000= 0.85%

(f) Need to note that statistics involves finding percentages, probability, and data analysis.

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .

-5, your answer was correct
