Probability questions~please help!!
Jenna teaches two courses in second semester, MTH1122 and MTH1030. Among
Jenna students 20 percent are MTH1122 students. As a consequence of Jennaís
teaching technique 10 percent of the MTH1030 students and 5 percent of the MTH1122
students develop an addiction to mathematics (wishful thinking, or course, but...).
a) What is the probability that one of Burkardís students who has been randomly chosen
is a matheholic?
b) One of Jennas students presents at the doctors with acute symptoms of maths addiction.
What is the probability that this student is an MTH1030 matheholic? Assumptions: A student who takes one course, does not take the other course. There
were no matheholics among the students before Jenna started teaching the course.
