Example 2

The completed two-way frequency table from Example 1 is shown below. It shows the results of a survey designed to help the Student Council choose a school-wide activity. Consider the following events that apply to a random student who participated in the survey. [list] [*][math]TEN[/math]: The student is in the tenth grade. [*][math]TWELVE[/math]: The student is in the twelfth grade. [*][math]FT[/math]: The student prefers a field trip. [*][math]TS[/math]: The student prefers a talent show. [/list] Compare [math]P(TEN \vert FT)[/math] and [math]P(FT \vert TEN)[/math]. Are [math]TEN[/math] and [math]FT[/math] independent? Compare [math]P(TWELVE \vert TS)[/math] and [math]P(TS \vert TWELVE)[/math]. Are [math]TWELVE[/math] and [math]TS[/math] independent? Interpret the results.
