Please don't hesitate to give a "thumbs up" in case you're satisfied with the answer.
a produces say 2x
b and c produce x
2% of A, and C are defective. 4% of b is defective. So, .02*2x+.02*x+.04*x = .1x is defective
all products are stocked together.
P(randomly selected product from the stock is defective) = total defective products/total products = (.1x)/(2x+x+x) = 1/40 = .025 or 2.5%
So, answer is 2.5%

5. The Brazos Initrode Group (BIG) has two factories that produce radios locally. When buying a BIG product from the store, the probability that it comes from factory A is 0.4; whereas it comes from factory B with probability 0.6. Each radio produced at factory A is defective with probability 0.2. Similarly, radios built at factory B are defective with probability 0.1 (a) 1 pt If you purchase a BIG radio, what is the probability that it is defective? (b)...

A company has 2 factories that produce digital cameras, Factory A and Factory.B. Factory produces 3 times as many digital cameras as Factory A does. 23% of digital cameras produced by factory A are defective. 8% of digital cameras produced by Factory B are defective. What is the probability that a digital camera was produced by factory.B given that it is defective? (Round to nearest percentage) A. 20 B. 10 C.40 D. 51 m.

A large firm uses three different types (A, B, and C) of raw materials to manufacture its product. Previous records show that 25% of the manufactured products are produced using material A, 50% using material B, and 25% using material C. If it is known that 5% of the product made with material A are defective, 2% made with material B are defective, and 5% made with C are defective. a. What is the probability that a product selected at...

(b) At a factory where bolts are produced, machines A, B, C produce respectively 25%, 35% and 40% of all bolts. Of the output of these machines, defects constitute 5%, 4% and 2% respectively. A bolt selected at random from the production turned out to be defective. What machine was the most likely to have produced this defective bolt? (give the probability it was this machine.) [5]

A company buys tires from three suppliers A, B and C. Supplier A has a record of delivering tires containing 8% defective, whereas supplier B has a defective rate of only 4% and supplier C has defective rate of 12%. Suppose 35% of current supply comes from supplier A, 30% from supplier C and rest from supplier B. If a tire is selected at random, find the probability: (a) that the tire is NOT defective; (b) given the selected tire...

s5. The chart below shows quality control information from three different factories that produce the exact same product. At random periods during production, an item is removed from the packaging belt and checked rigorously to ensure that it is meeting corporate manufacturing standards. A battery of tests is performed on the selected item, and it is ranked on a scale of 0 to 9 100 (0 is a complete failure rendering the product useless, and 100 is an item in...

Twice as many automobile transmissions are made in Plant A than in Plants B and C. Equal numbers are made in Plants B and C. But all are stored in the same warehouse. Past experience has recorded 1.0 percent of transmissions from Plant A, 1.8 transmissions from Plant B, and 1.2 transmissions from Plant C are defective. Keep 4 significant digits. a) What is the probability a transmission selected at random from the warehouse is defective? b) A transmission is...
