I really like watching films directed by the Coen brothers. Say that they make up about 40% of all the movies I watch. However, my wife Eve isn’t so enthusiastic. Suppose that we only watch Coen brothers movies about 20% of the time if we’re watching a film together. However, if I’m watching a film without Eve, then there’s about a 70% chance that the film will be by the Coen brothers. In other words, P(Coen brothers) = 0.4 P(Coen brothers | Eve) = 0.2 P(Coen brothers | Not Eve) = 0.7.
a) Show that about 60% of the time, I watch movies with Eve, i.e., P(Eve)=0.6. Clearly show all workings. (Hint: Use the fact that P(A)= P(A,B)+P(A, not B).)
b) Suppose I am watching a Coen brothers movie. What is the probability that Eve is watching with me, P(Eve | Coen brothers)?
