Consider a company that assembles computers. The probability of a faulty assembly of any computer is p. The company therefore subjects each computer to a testing process.This testing process gives the correct result for any computer with a probability of q. What is the probability of a computer being declared faulty?

A | pq + (1 - p)(1 - q) |

B | (1 - q) p |

C | (1 - p) q |

D | pq |
