Suppose that a factory has two machines, Machine A and Machine B, both producing jPhone touch screens. Forty percent of their touch screens come from Machine A and 60% of their touch screens come from Machine B. Ten percent of the touch screens produced by Machine A are defective and five percent of the touch screens from Machine B are defective. If I randomly choose a touch screen from those produced by both machines and find that it is defective, what is the probability that it came from machine A?

Detecting terrorists is a real problem, one that causes governments to spend millions per year. A particular surveillance system has been developed which correctly identifies a future terrorist 99% of the times and detects someone who is not a future terrorist 99.9% of times. Suppose that in a population of 300 million, there are 1000 potential/future terrorists. If one of these 300 million is randomly selected and scrutinized by the system, what is the probability that the person selected is actually a future terrorist? Also explain if the value of this probability makes you uncomfortable about using a surveillance system? Explain.
A company orders the memory for their devices from two suppliers. Supplier A supplies 82% of the memory while supplier B supplies the remainder. Previous testing has shown that 1.1% of Supplier A's memory is defective and 1.9% of Supplier B's memory is defective. A randomly selected memory chip is defective. Find the probability it came from Supplier B.
A company buys microchips from three suppliers I, II and III. Supplier I has a record of providing microchips that contain 10% defective; supplier a defective rate of 5% and supplier III has a defective rate of 3%.

A certain blood test is 99.5% effective at detecting Foreign Bloodborne Pathogens (such as the hepatitis virus) in human blood. If two people who take this test are selected at random, what is the probability both tests correctly detect a Foreign Bloodborne Pathogen? If ten people who take this test are selected at random, what is the probability all tests correctly detect a Foreign Bloodborne Pathogen? If 1,000 people who take this test are selected at random, what is the probability at least one test FAILS to detect a Foreign Bloodborne Pathogen?
According to Mendel’s theory, if tall and colorful plants are crossed with short and colorless plants, the corresponding probabilities are 9/16, 3/16, 3/16, and 1/16 for tall and colorful, tall and colorless, short and colorful, and short and colorless, respectively. If 8 plants are selected, find the probability that 1 will be tall and colorful, 3 will be tall and colorless, 3 will be short and colorful, and 1 will be short and colorless.(4 decimal digits)
The vast majority of European vehicles sold in the world (BMW, Audi, Mercedes- Benz, etc...) receive their transmissions from either ZF Friedrichshafen AG or Continental AG. After the acquisition of TRW by ZF, ZF AG supplied 69% of transmissions, and Continental AG supplied 31%. If three European cars are randomly selected, what is the probability that 2 of the cars use ZF transmissions and 1 use Continental AG transmission? Enter your answer in percent terms (for example 12.5% must be entered as 12.5).

A manufacturer wishes to estimate the accuracy of its final visual inspection process. A random sample of 180 devices is selected from production. An item is defective or “bad” if it contains at least one visually noticeable cosmetic defect. The process improvement team agrees that the sample contains 27 bad items and 153 good items. The team gives the items to a “certified” operator for inspection. The operator rejects 10 good pieces and accepts 11 bad pieces and classifies the remainder correctly. What is the probability that the inspector will reject an item? P(inspector will reject an item) = ________%. Enter value using one decimal place.
