Based on the number of voids, a ferrite slab is classified as either high medium or low. Historically, 6% of the slabs are classified as high, 82% as medium and 12% as low. A sample of 20 slabs is selected for testing. Let X, Y, and Z denote the number of slabs that are independently classified as high, medium, and low, respectively. Determine the following. Round your answers to four decimal places (e.g. 98.7654). (a) P(X = 1, Y = 17, Z =3) (b) P(X = 1, Y = 17, Z = 3) (c) P(X = 1) (d) E(X) (a) (b) (c) (d)
