EXE ISE 4 A furniture manufacturer ordered a stack of plywoods with a spesific measurement from a supplier Suppose that 0.03% of the plywoods received were unfit to use. Let X represents number of unfit plywoods. In a random sample of 10 000, calculate: i P(X 3) i. P(Xs 2) ii.P (1s X v. E(X) and Var (X). How would you interpret the mean and variance?
