o A course in statistics is one of the most difficult at the local university. Because of this, for the past decade the university has arranged for teaching assistants to hold frequent discussion sessions as part of the course. Since the inception of the discussion sessions, 60% of the students enrolled in the course regularly attended the sessions, and the other 40% did not. Students regularly attending the sessions have performed better than those not regularly attending. In particular, 65%...

6. Students in one statistics course need to earn a grade of at least C, otherwise they need to repeat the course. It is also known that 85% of all students who attend class regularly will earn a grade of at least C, while only 30% of those students who do not attend class regularly will earn a grade of at least C. Historically, 80% of all students in this course attend class regularly. You must explicitly define any events...
