Answer 1

To find P(more than 1 hour of TV | 6th period class), we need to look at the students in the 6th period class who watched more than 1 hour of TV.

P(more than 1 hour of TV | 6th period class) = (Number of students in 6th period class who watched more than 1 hour of TV) / (Total number of students in the 6th period class)

From the table, we see that the number of students in the 6th period class who watched more than 1 hour of TV is 13.

The total number of students in the 6th period class is 13 + 10 = 23.

P(more than 1 hour of TV | 6th period class) = 13 / 23 = 0.565 (rounded to the nearest thousandth)

Therefore, the probability that a student in the 6th period class watched more than 1 hour of TV last night is 0.565.
