The conditional relative frequency table was generated using data that compared a student’s grade level and whether or not they
are involved in after-school activities. A 4-column table with 3 rows. The first column has no label with entries 10th grade, 11th grade, total. The second column is labeled after-school activities with entries 0.43, 0.55, 0.49. The third column is labeled no after-school activities with entries 0.57, 0.45, 0.51. The fourth column is labeled total with entries 1.0, 1.0, 1.0.
Given that a student is in 10th grade, what is the probability that the student is also not involved in after-school activities?
