Use Bayes' rule to find the indicated probability.Two shipments of components were received by a factory and stored in two separate bins. Shipment I has 2% of its contents defective, while shipment II has 5% of its contents defective. If it is equally likely an employee will go to either bin and select a component randomly, what is the probability that a defective component came from shipment II?

Write an algebraic expression for the quantities being compared.The first angle of a triangle is triple the third angle. The second angle of a triangle is 20 degrees less than the third angle.
A. first angle = x - 20 second angle = 3x third angle = x B. first angle = 3x second angle = x - 20 third angle = x C. first angle = 3x + 20 second angle = x - 20 third angle = x D. first angle = x second angle = x - 20 third angle = 3x
