It is a well-known fact that 50% of the general population are rascals (p(r) = 0.5) and 50% of the general population are not rascals (p(rc ) = 0.5). furthermore, scientists have determined that about 90% of rascals wear a top hat at all times, while only 30% of non-rascals wear top hats.
suppose that you meet a person who is wearing a top hat. given the information that they are wearing a top hat, what is the probability that they are a rascal?
a. 0.09
b. 0.45
c. 0.6
