First, we need to find the total number of students in the 6th period class who watched more than 1 hour of TV. This would be 13 students.
Next, we need to find the total number of students in the 6th period class, which would be 13 + 10 = 23 students.
Therefore, P(more than 1 hour of TV | 6th period class) = 13/23 ≈ 0.565
So, the answer is b) 0.565.
The table shows the results of a survey of students in two math classes. Find P(more than 1 hour of TV | 6th period class). Round to the nearest thousandth.
