Question

A college administration has conducted a study of 166 randomly selected students to determine the relationship between satisfaction with academic advisement and academic success. They obtained the following​ information: Of the 62 students on academic​ probation, 29 are not satisfied with​ advisement; however, only 23 of the students not on academic probation are dissatisfied with advisement. What is the probability that a student selected at random is not on academic probation and is not satisfied with​ advisement?

Answer 1

It would help if we represent the information in form of two-ways table as shown below 

The number of students who are not on probation is 104 students
There are 23 students who are not on probation and is satisfied is 81 students

The probability of students not on probation and is satisfied is 81/104
