Results on the Bar Exam of Law School Graduates

The table above summarizes the results of 200 law school graduates who took the bar exam. If one of the surveyed graduates who passed the bar exam is chosen at random for an interview, what is the probability that the person chosen did `ul("not")` take the review course?

Human blood can be classified into four common blood types—A, B, AB, and O. It is also characterized by the presence (+) or absence (–) of the rhesus factor. The table above shows the distribution of blood type and rhesus factor for a group of people. If one of these people who is rhesus negative (–) is chosen at random, the probability that the person has blood type B is 1/9 . What is the value of x ?

The table above summarizes the result of a survey taken in which 240 adults were asked about their education level and current annual salary. If a participant who reported earning $35,000 or more per year is selected at random, what is the best estimate of the probability that the person does not have a graduate school degreee?

The data in the table above were produced by a sleep researcher studying the number of dreams people recall when asked to record their dreams for one week. Group X consisted of 100 people who observed early bedtimes, and Group Y consisted of 100 people who observed later bedtimes. If a person is chosen at random from those who recalled at least 1 dream, what is the probability that the person belonged to Group Y ?

Question 4-6 refer to the above table, which summarizes the result of a survey of the student body of a high school about club membership in which each student enrolled in the high school enumerated the clubs in which they were members. Q. If a students is selected at random, what is the probability that the student does not belong to 3 or more clubs?

Of the students in a school, it is known that 30% have 100% attendance and 70% students are irregular. Previous year results report that 70% of all students who have 100% attendance attain A grade and 10% irregular students attain A grade in their annual examination. At the end of the year, one student is chosen at random from the school and he was found to have an A grade. What is the probability that the student has 100% attendance ? Is regularity required only in school ? Justify your answer.
