Code Churn is a common metric used to measure the efficiency and productivity of software engineers and computer programmers. It's usually measured as the percentage of a programmer's code that must be edited over a short period of time. Programmers with higher rates of code churn must rewrite code more often because of errors and inefficient programming techniques. The following table displays sample information for 10 computer programmers. Total Lines of Code Number of Lines of Code Programmer Written Requiring Edits Liwei 24,830 5,432 Andrew 16,210 2,114 Jaime 29,750 11,596 Sherae 26,934 4,667 Binny 22,536 5,689 Roger 24,900 2,310 Dong-Gil 21,369 2,650 Alex 16,842 4,505 Jay 31,658 3,657 Vivek 23,887 4,321 Use the data in the table above and the relative frequency method to determine probabilities that a randomly selected line of code will need to be edited for each programmer.

Question
Code Churn is a common metric used to measure the efficiency and productivity of software engineers and computer programmers. It's usually measured as the percentage of a programmer's code that must be edited over a short period of time. Programmers with higher rates of code churn must rewrite code more often because of errors and inefficient programming techniques. The following table displays sample information for 10 computer programmers.
Total Lines of Code | Number of Lines of Code | |
Programmer | Written | Requiring Edits |
Liwei | 24,830 | 5,432 |
Andrew | 16,210 | 2,114 |
Jaime | 29,750 | 11,596 |
Sherae | 26,934 | 4,667 |
