Given that a machine produces defective parts with three different probabilities depending on its state of repair.

condition             Good order         Wearing down               Needs main   Total

Prob                       0.8                            0.1                                   0.1              1

Defective               0.02                          0.1                                   0.3

Joint prob              0.016                         0.01                                0.03        0.056

a) 0.016

b) total = 0.056

c) If not defective from needs maintenance

Prob for not defective = 0.8*0.98+0.1*0.9+0.1*0.7\\=0.784+0.09+0.07\\=0.944

From machine that needs maintenance = 0.07

So reqd prob = \frac{0.07}{0.944} \\=0.0741
