At a factory that produces pistons for cars, Machine i produced 369 satisfactory pistons and 41 unsatisfactory pistons today. Machine 2 produced 350 satisfactory pistons and 150 unsatisfactory pistons today. Suppose that one piston from Machine 1 and one piston from Machine 2 are chosen at random from today's batch. What is the probability that the piston chosen from Machine 1 is unsatisfactory and the piston chosen from Machine 2 is satisfactory? Do not round your answer. (If necessary, consult...

At a factory that produces pistons for cars, Machine 1 produced 792 satisfactory pistons and 198 unsatisfactory pistons today. Machine 2 produced 540 satisfactory pistons and 360 unsatisfactory pistons today. Suppose that one piston from Machine 1 and one piston from Machine 2 are chosen at random from today's batch. What is the probability that the piston chosen from Machine 1 is satisfactory and the piston chosen from Machine 2 is unsatisfactory ?

A machine that manufactures automobile pistons is estimated to produce a defective piston 3% of the time. Suppose that this estimate is correct and that a random sample of 90 pistons produced by this machine is taken. a. Estimate the number of pistons in the sample that are defective by giving the mean of the relevant distribution (that is, the expectation of the relevant random variable). Do not round your response. b. Quantify the uncertainty of your estimate by giving...

In one factory, the light bulb is produced by three machines. The first machine produces 20% of the total production of the factory. The second machine produces 30% of the total production of the factory. The third machine produces 50% of the total production of the factory. The percentage of damaged production of the first machine is 1% and the percentage of damaged production of the second machine is 4% and the percentage of damaged production of the third machine...
In a factory, machine A produces 60% of the daily output, and machine B produces 40% of the daily output. After quality control process, 2% of machine A's output is defective, and 3% of machine B's output is defective. If an item was inspected at random,
In a factory, machine A produces 60% of the daily output, and machine B produces 40% of the daily output. After quality control process, 2% of machine A's output is defective, and 3% of machine B's output is defective. If an item was inspected at random, 1- What is the probability that the item is defective? 2- What is the probability that the item was produced by machine A given that it was found defective?

Assume that a factory has two machines ??A_1 and ??A_2 . Past records shows that machine ??A_1 produces 60% of the items of output and machine ??A_2 produces 40% of the items. Further, 2% of the items produced by machine ??A_1 were defective and only 1% produced by machine ??A_2 were defective. If a detective item is drawn at random, what is the probability that it was produced by machine ??A_1 ?
