A heating equipment manufacturer purchases heating elements from three different suppliers: 30% Som, 50% Dom and 20% by Tom. The elements are mixed in a supply bin prior to inspection and installation. Based on past experience, 10% of the Som elements are defective, compared to only 5% of those supplied by Dom, and just 4% of those from Tom. An assembly worker randomly selects an element for installation. What is the probability that the defective element was supplied by Dom?
