Analysis of the Given Information

According to the given information, there were a total of 17 students who failed the math exam, 18 students who failed the literature exam, and 2 students who failed both math and Russian language exams. Additionally, 4 students failed both literature and math exams, 6 students failed both Russian language and literature exams, and 8 students received a grade of "2" (presumably a failing grade) in math, while 7 students received a grade of "2" in Russian language. One student failed only the history exam.

We are asked to determine the number of students who failed the Russian language exam and the number of students who received only one failing grade in literature. We are also asked to find the total number of students who received failing grades in the college.

Finding the Number of Students Who Failed the Russian Language Exam

To find the number of students who failed the Russian language exam, we need to subtract the number of students who failed both math and Russian language exams and the number of students who failed both literature and Russian language exams from the total number of students who failed the Russian language exam.

Let's calculate it step by step:

1. Total number of students who failed the Russian language exam = Total number of students who failed the literature exam - Number of students who failed both literature and Russian language exams - Total number of students who failed the literature exam = 18 - Number of students who failed both literature and Russian language exams = 6 - Total number of students who failed the Russian language exam = 18 - 6 = 12

Therefore, 12 students failed the Russian language exam.

Finding the Number of Students Who Received Only One Failing Grade in Literature

To find the number of students who received only one failing grade in literature, we need to subtract the number of students who failed both literature and math exams and the number of students who failed both literature and Russian language exams from the total number of students who failed the literature exam.

Let's calculate it step by step:

1. Total number of students who received a failing grade in literature = 18 2. Number of students who failed both literature and math exams = 4 3. Number of students who failed both literature and Russian language exams = 6 4. Number of students who received only one failing grade in literature = Total number of students who received a failing grade in literature - Number of students who failed both literature and math exams - Number of students who failed both literature and Russian language exams - Number of students who received only one failing grade in literature = 18 - 4 - 6 = 8

Therefore, 8 students received only one failing grade in literature.

Finding the Total Number of Students Who Received Failing Grades in the College

To find the total number of students who received failing grades in the college, we need to add the number of students who failed the math exam, the number of students who failed the literature exam, and the number of students who failed the Russian language exam. However, we need to subtract the number of students who failed both math and Russian language exams, the number of students who failed both literature and math exams, and the number of students who failed both literature and Russian language exams. This is to avoid double-counting those students.

Let's calculate it step by step:

1. Total number of students who received failing grades in the college = Total number of students who failed the math exam + Total number of students who failed the literature exam + Total number of students who failed the Russian language exam - Number of students who failed both math and Russian language exams - Number of students who failed both literature and math exams - Number of students who failed both literature and Russian language exams - Total number of students who failed the math exam = 17 - Total number of students who failed the literature exam = 18 - Total number of students who failed the Russian language exam = 12 - Number of students who failed both math and Russian language exams = 2 - Number of students who failed both literature and math exams = 4 - Number of students who failed both literature and Russian language exams = 6 - Total number of students who received failing grades in the college = 17 + 18 + 12 - 2 - 4 - 6 = 35

Therefore, 35 students received failing grades in the college.

In summary: - The number of students who failed the Russian language exam is 12. - The number of students who received only one failing grade in literature is 8. - The total number of students who received failing grades in the college is 35.
