Q4(8). A manufacturer uses three different suppliers for a particular component. In current inventory, there are 450 parts from supplier A, 350 from supplier B, and 200 from supplier C. The manufacturer found that 0.2% of parts from supplier A is defective; 0.5% of parts from supplier B is defective; 0.6% of parts from supplier C is defective. Let A, B, C denote the events that the part came from supplier A,B,C, respectively. 1(3). Based on the inventory mix, determine P(A), P(B), P(C). 2(5). If one randomly selected part is defective (event D), determine the probability that it came from supplier C.
