=+66. In an experiment, 25 laminated glass units configured in a particular way are subjected to an impact test (cf.

“Performance of Laminated Glass Units Under Simulated Windborne Debris Impacts,” J. of Architectural Engr., 1996: 95–99). We are interested in the number of units that sustain an inner glass ply fracture. Suppose that the long-run proportion of all such units that fracture is .20. In the long run, for what proportion of such experiments will the number of fractures be

a. At least 10?

b. At most 5?

c. Between 5 and 10 inclusive?

d. Strictly between 5 and 10?
