At a university with 1,000 business majors, there are 200 business students enrolled in an introductory statistics course. Of these 200, 50 are also enrolled in an introductory accounting course. There are an additional 250 business students enrolled in accounting but not enrolled in statistics. If a business student is selected at random, what is the probability that the student is not enrolled in accounting?

The probability to not to enroll in accounting = 70%

Step-by-step explanation:

Total business students = 1000

Stats students = 200

Students with stats and accounts = 50

So, only stats student = 200 – 50 = 150

Only accounts students = 250

The probability of students not enrolled in accounting will be the probability to enrolled in stats.

Total accounts students = 50+ 250 = 300

Probability of accounts students = 300 / 1000 = 0.3 or 30 %

So, probability to not accounting student = 100% - 30% = 70%

if im undersanding the question correctly, its organized from 10

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
