Jackman industries has two service departments, maintenance and power, and two operating departments, production and assembly. management has decided to allocate maintenance costs on the basis of direct-labor hours in each department and power costs on the basis of machine hours. the following data were experienced by the company in the current period: maintenance power production assembly direct labor hours 0 400 4,000 2,000 machine hours 2,000 0 8,400 1,600 department direct costs $ 9,000 $ 20,000 $ 70,000 $ 50,000 what is the total service cost allocated to the production department during the period if the direct method of cost allocation is used?

Part (a) is relatively straight forward.there are 4 aces in a standard 52-card deck. so the probability that an ace is picked is just 4/52.part (b): note that there are 4 suits in a standard 52-card deck. so picking hearts will be 13/52 or 1/4.part (c): the probability condition or means we need to add the two probabilities because we do not want them simultaneously. so, we end up getting pr(ace) + pr(heart).from part (a), we found that picking an ace had a probability of 4/52, which is reduced down to 1/13.from part (b), we found that picking a heart had a probability of 1/4.so, the probability of an ace or a heart is 1/13 + 1/4 = 4/52 + 13/52 = 17/52.
