In a class of students, the following data table summarizes how many student passed a test and complete the homework due the day of the test. What is the probability that a student chosen randomly from the class passed the test or completed the homework? & }(c) Passed the test & Failed the test Completed the homework & 12 & 6 Did not complete the homework & 3 & 4

To find the probability that a student chosen randomly from the class either passed the test or completed the homework, we need to consider the total number of students who either passed the test or completed the homework, and then divide that by the total number of students in the class.First, let's identify the number of students who passed the test, completed the homework, or both. According to the table:- 12 students passed the test and completed the homework.- 3 students passed the test but did not complete the homework.- 6 students failed the test but completed the homework.Now, let's calculate the total number of students who passed the test or completed the homework: Next, we need to find the total number of students in the class. We can do this by adding all the numbers in the table: Now we can calculate the probability that a student chosen randomly from the class passed the test or completed the homework: So, the probability that a student chosen randomly from the class passed the test or completed the homework is .
