Question

in a class of students the following data table summarizes how many students pass a test and completed the homework due the day of the test what is the possibility that a student chosen randomly from the class failed the test

Answer 1

From the table,

Total number of students that failed the test = 2 + 7 = 9

The total number of students that participated = 10 + 3 + 2 + 7 = 22

The possibility that a student chosen randomly from the class failed the test = ​Total number of students that failed the test divided by the total number of students that participated

= 9/22

Hence, the possibility that a student chosen randomly from the class failed the test is 9/22
