Solution :
Faulty electrical connects = P(A) = 0.80
Mechanical defects = P(B) = 0.92
Mechanical defects are related to loose keys = P(C/B) = 0.27
Improper assembly = P(D/B) = 0.73
Defective wires = P(E/A) = 0.35
Improper connections = P(F/A) = 0.13
Poorly welded wires = P(G/A) = 0.52
Now, the probability due to loose keys = 0.27 x 0.92 = 0.2484
Improperly connected = 0.13 x 0.80 = 0.1040
Poorly welded wires = 0.52 x 0.80 = 0.4160
So, the probability that a failure is due to improperly connected or poorly welded wires = 0.1040 + 0.4160
= 0.5200

Answer:
148.5 meters^3
Step-by-step explanation:
The volume of a rectangular prism can be found using the following formula.
V=l*w*h
The length is 6 meters. The height is 4.5 meters. The width is 5.5 meters. Substitute these values into the formula.
V=6*5.5*4.5
Multiply all the values together
V=33*4.5
V=148.5
Add appropriate units. Volume uses units^3 and the units are meters.
V=148.5 meters^3
The volume of the rectangular prism is 148.5 cubic meters.
