Certain pieces made by an acoustic lathe are subject to three kinds of defects X, Y,Z. A sample of 100 pieces was inspected with the following results: 2.1% had type X defect.
2.4% had type Y .
2.8 had typre Z
0.3 had both X and Y
0.4 had both X and Z
0.6 had both Y and Z
Then Find:
A. What percent had none of these defects.
B. What percent had at least one of these defects.
C. What percent were free of type X and/ or type Y defects?
D. What percent had not more than one of these defects?

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?
