Answer:
Step-by-step explanation:
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](https://tex.z-dn.net/?f=0.8%2A0.98%2B0.1%2A0.9%2B0.1%2A0.7%5C%5C%3D0.784%2B0.09%2B0.07%5C%5C%3D0.944)
From machine that needs maintenance = 0.07
So reqd prob = ![\frac{0.07}{0.944} \\=0.0741](https://tex.z-dn.net/?f=%5Cfrac%7B0.07%7D%7B0.944%7D%20%5C%5C%3D0.0741)
Use proportions here - 8/5.2 = 96/width of actual car. using cross multiplication, 5.2*96 = 8x. this gives you 499.2 = 8x. divide both sides by eight to get x=62.4. the width of the actual car is 62.4 inches.
It would go over the five, so im guessing the hundreds
