2 5 points A Microchip company found quarts in commercial quantities in two different developing countries X Y To take advantage of the reduced cost of labor the company has built two independent foreign pre processing firms one in each location to produce silicon from quarts for its chip Industry However the production of silicon is sometimes stopped due to disrupted electricity supply at these locations In location X there is a 12 chance that there will be no electricity supply during production hours Similarly there is a 21 chance of the same problem in location Y a 1 5 points At a particular random time find the probability that only one of the foreign firms is operating without electricity disruption b 1 point At a randomly selected time determine the probability that at least one of the foreign firms is operating without electricity disruption c 1 point Calculate the probability that neither of the foreign firms is producing silicon because there was no electricity supply d 1 5 points If at least one of the foreign firms is producing silicon at a particular time find the
