১২ Contingency Tables and Conditional Probability: Homework and Passing a Course A teacher categorized students by whether they regularly completed their homework (or not) and whether they passed the course (or not). The data are in the table below. Completed HW Did not Complete HW Total 7. 17 Passed the Course 26 33 23 9. 32 Did not Pass the Course Total 24 A student from the class is randomly selected. Determine the following probabilities. Enter your results as percents rounded to two decimal places. What is the probability a student completed the HW? What is the probability a student passed the course and did not complete the HW? What is the probability a student did not pass the course or completed the HW? What is the probability a student passed the course given that they completed the HW? Question Help: Written Example MMessage instructor Submit Question Jump to Answer 20 43,324 MAR tv 280 8. 166328
