6.The company has two machines that produce certain items. Machine 1 produces 30% of thethe items, and Machine 2 produces 70% of the items.Machine 1 produces 2% of defective items and Machine 2 produces 4% of defective items.All items produced by both machines during long period of time are placed into the box andthoroughly mixed.a. The probability that an item randomly selected from the box is defective isb. If an item randomly selected from the box is defective, probability that it is produced onMachine 2 is_Assuming that the event "an item randomly selected from the box is defective "is denoted by D,the event "An item randomly selected from the box is produced by Machine 1 "is denoted by M1,the event "An item randomly selected from the box is produced by Machine 2 " is denoted by M2,show your work in answering the questions a. and b.

P(M1) = 0.3P(D| M1) = 0.02P(M2) = 0.7P(D| M2) = 0.04
