In a shipment of laptop computers, 4% have a faulty keyboard, 6% have a faulty screen, and 1% have a faulty keyboard and a faulty screen.

(a) What is the probability that a randomly selected laptop has at least one of these defects?

(b) Given that a laptop has a faulty keyboard, what is the probability that it also has a faulty screen?

(c) Given that a laptop does not have a faulty keyboard, what is the probability that its screen is also not faulty?
