Round your answer to at least two decimal places.

|---|---|---|---|---|
| Both parents smoke | Only one parent smokes | Neither parent smokes | ||
| Individual\'s smoking habits | Smokes | 28 | 37 | 42 |
| Does not smoke | 22 | 36 | 33 |
Solution
To calculate this, look at row of \"smokes\", relative freq = desired/ total
relative freq = 42 / ( 28 + 37 + 42) = 0.39252336448598130841
