Calculate Total Students: First, we need to determine the total number of students in the class. We do this by adding up all the students in each category.Total students =(Passed the test and Completed the homework)+(Failed the test and Completed the homework)+(Passed the test and Did not complete the homework)+(Failed the test and Did not complete the homework)Total students =10+5+3+4Total students =22
Calculate Passed Test or Completed Homework: Next, we calculate the number of students who passed the test or completed the homework. To avoid double-counting the students who both passed the test and completed the homework, we will add the number of students who passed the test to the number of students who completed the homework and then subtract the number of students who did both.Number of students who passed the test or completed the homework =(Passed the test)+(Completed the homework)−(Passed the test and Completed the homework)Number of students who passed the test or completed the homework =(10+3)+(10+5)−10Number of students who passed the test or completed the homework =13+15−10Number of students who passed the test or completed the homework =28−10Number of students who passed the test or completed the homework =18
Calculate Probability: Now, we calculate the probability that a student chosen randomly from the class passed the test or completed the homework. The probability is the number of students who passed the test or completed the homework divided by the total number of students.Probability = Number of students who passed the test or completed the homework / Total studentsProbability = 2218
Simplify Probability: Finally, we simplify the fraction to get the probability in simplest form. Probability = 2218Probability = 119
