One thousand sheets of aluminum alloy produced by the same manufacturer were examined for surface flaws. Assume surface flaws occur randomly and independently at a constant rate with an average of 4 flaws per sheet. Sheets are all the same size.

a) [3 points] What is the probability that a randomly chosen sheet contains more than 1 surface flaw?

b) [3 points] When 10 sheets are picked at random, what is the probability that 6 of these sheets have more than 1 surface flaw on them?

c) [4 points] Given that a sheet has more than 1 surface flaw on it, find the probability that it has exactly 10 surface flaws.

Question 15 1 pts The figure shows a cubical Gaussian Surface; at the center of the cube is a point charge (the circle) with charge 189. What could explain the flux through BOTTOM face of the Gaussian Surface being 2q,/Eg? TOP BOTTOM An unshown positive charge located above the TOP face of the Gaussian Surface. An unshown negative charge located below the BOTTOM face of the Gaussian Surface. None of the other answers can explain this situation. An unshown positive charge located below the BOTTOM face of the Gaussian Surface. O An unshown positive charge located within the Gaussian Surface.The potential inside a conducting sphere of radius R is a. directly proportional to radius "r" of the Gaussian Surface. b. Inversely proportional to the radius "r" of the Gaussian surface. C C. a constant. d. zero. O e. inversely proportional to the square of the radius "r" of the Gaussian surface. O F. infinite.13. The figure below shows a spherical Gaussian surface of radius R. A very long thin rod passing through the center of the sphere has a uniform linear negative charge density -2. A charge -q is located inside the Gaussian surface. Located outside is another charge +q. What is the ner electric flux through the Gaussian surface? R spherical Gaussian surface A. La B. C. D. E
