According to a global survey of 4,400 parents of children between the ages of 14 to 17, 44% of parents spy on their teen’s Facebook account (msnbc.com, April 25, 2012).

Assume that American parents account for 10% of all parents of teens with Facebook accounts, of which 60% spy on their teen’s Facebook account. Suppose a parent is randomly selected, and the following events are defined: A = selecting an American parent and B = selecting a spying parent.

a. Based on the above information, what are the probabilities that can be established? Would you label them as subjective, empirical, or classical?

b. Are the events A and B mutually exclusive and/or exhaustive? Explain.

c. Are the events A and B independent? Explain.

d. What is the probability of selecting an American parent given that she/he is a spying parent?
