The firm that manufactures patriot missiles purchases theguidance circuits from three different suppliers. Supplier Aprovides 30% of the guidance circuits and those circuits have afault probability of pA =0.02, whereas the circuits from supplierB, which provides 25% of those purchased, have a fault probabilityof pB =0.025. The guidance circuits purchased from supplier C havepC =0.01. If a batch of 200 missiles is fired during a particularstrategic offensive and three of the missiles fail to track totarget, what is the probability that the batch of missilescontained guidance circuits obtained from supplier B?
