Suppose it is known that 1 part in 1000 produced by an aircraft supplier is bad. each part can be screened for defects using x-rays. if the part is bad, the x-ray test will detect it with probability 0.999. if the part is good, there is a probability of 0.002 that it is erroneously indicated as bad by the x-ray test. for one randomly selected part, the test shows that it is bad. what is the probability that it is really bad (hint: this is a conditional probability)?

Ariana starts with 100 milligrams of a radioactive substance. the amount of the substance decreases by 20% each week for a number of weeks, w. the expression 100(1−0.2)w finds the amount of radioactive substance remaining after w weeks. which statement about this expression is true? a) it is the difference between the initial amount and the percent decrease. b) it is the difference between the initial amount and the decay factor after w weeks. c) it is the initial amount raised to the decay factor after w weeks. d) it is the product of the initial amount and the decay factor after w weeks.
