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.
Did You Watch More Than One Hour of TV Last Night?
Yes No
3rd period class 11 6
6th period class 13 10
P(more than 1 hour of TV | 6th period class) = P(more than 1 hour of TV and 6th period class) / P(6th period class)
P(more than 1 hour of TV and 6th period class) = 13
P(6th period class) = 13 + 10 = 23
P(more than 1 hour of TV | 6th period class) = 13/23 ≈ 0.565
Therefore, the probability of a student watching more than 1 hour of TV given that they are in the 6th period class is approximately 0.565.
