Probability of Defective Resistors: DeMoivre-Laplace Theorem
A manufacturer of electronic equipment buys 900 resistors for which the probability of any single resistor being defective is p = 0.01. What is the probability that:
(a) Exactly two of the resistors are bad ?
(b) None of the resistors are bad ?
(c) Exactly 9 of the resistors are bad ? (Use the DeMoivre-Laplace Theorem).
