Question

the conditional relative frequency table was generated using data that compared a students grade level and whether or not they are involved in after - school activities. given that a student is in 10th grade, what is the probability that the student is also not involved in after - school activities? after - school activities no after - school activities total 10th grade 0.43 0.57 1.0 11th grade 0.55 0.45 1.0 total 0.49 0.51 1.0 0.43 0.45 0.55 0.57

Explanation:

Step1: Identify relevant data

We look at the row for 10th - grade in the conditional - relative frequency table.

Step2: Find the probability

The probability that a 10th - grade student is not involved in after - school activities is given in the "No After - School Activities" column for 10th grade.

Answer:

0.57
