Solve the problem.Maxwell's theory of electromagnetic waves established that electromagnetism moved through space in waves. Under certain conditions, an equation that Maxwell used to explain the motion of such waves would take the form  where ? is the angle of incidence of the original wave, ? is the angle of incidence of the wave when reflected, A is the amplitude of the original wave, and B is the amplitude of the wave when reflected.

Use Bayes' rule to find the indicated probability.Two stores sell a certain MP3 players. Store A has 34% of the sales, 5% of which are of defective items, and store B has 66% of the sales, 1% of which are of defective items. The difference in defective rates is due to different levels of pre-sale checking of the product. A person receives a defective item of this product as a gift. What is the probability it came from store B?

A. 0.275 B. 0.22 C. 0.5667 D. 0.7083
