The class registrations of 100 students are analyzed. It is found that 50 students study Applied Mechanics, 45 study Chemistry, and 15 studied both Applied Mechanics and Chemistry.
-
(a) If one of these students is selected at random, find the probability that
i. the student took applied mechanics or chemistry. ii. the student did not take either of these subjects.
iii. the student took chemistry but not applied mechanics.
-
(b) Are studying Applied Mechanics and studying Chemistry mutually exclusive events? Why or why not?
-
i. would be p[.80]?
ii. p[.05]?
iii. I can't come up with a solution

Do students reduce study time in classes where they achieve a higher midterm score? In a Journal of Economic Education article (Winter 2005), Gregory Krohn and Catherine O'Connor studied student effort and performance in a class over a semester. In an intermediate macroeconomics course, they found that "students respond to higher midterm scores by reducing the number of hours they subsequently allocate to studying for the course." Suppose that a random sample of n = 8 students who performed well...

Q1)
Consider two events P and Q.
a. Write the general formula used to calculate the probability
that either event P occurs or Q occurs or both occur.
b. How does this formula change if:
i. Events P and Q are disjoint (i.e., mutually exclusive of each
other).
ii. Events P and Q are nondisjoint events that are statistically
independent of each other.
iii. Events P and Q are nondisjoint events that are
statistically dependent of each other.

(a) In a study into consumer behaviour and service dissatisfaction, it is found that the probability of event A, that a consumer will switch their mobile phone service provider, is 0.6, and the probability of event B, that a consumer will switch their home electricity supply provider, is 0.5. The probability that a consumer will switch their mobile phone service provider and will switch their home electricity supply provider, P(A ∩ B), is found to be 0.42. What is the...
