Suppose that an eddy current nondestructive evaluation technique for identifying cracks in clinical metal parts has a probability of around .20 of detecting a single crack of length .003 in. in a certain material. Suppose further that 8 specimens of this material, each containing a single crack of length .003 in., are inspected using this technique. Let W be the number of these cracks that are detected. Use an appropriate probability model and evaluate the following:

(a) P[W = 6]. (b) P[W ? 6].

(d) P[3?W?6]

(e) E(W).

(f) Var(W).
