(b) A box contains eight resistors and the probability that a resistor functions = 0.35. What is the probability that at least 2 resistors are functioning?

Refer to the sample data for pre-employment drug screening shown below. If one of the subjects is randomly selected, what is the probability that the test result is a false positive? Who would suffer from a false positive result? Why? Help Pre-Employment Drug Screening Results Positive test result Negative test result Drug Use Is Not Indicated Drug Use Is Indicated Subject Uses Drugs Subject Is Not a Drug User 38 4 15 28 The probability of a false positive test result is (Round to three decimal places as needed.)

P(z < 0.76)Express the probability as a decimal rounded to 4 decimal places.

A coin is in one of 5 boxes. The probability that it is in the ith box is (i/15). If you search in the ith box and it is there, you find it with probability (4/5). Find the probability that the coin is in the 3rd box given that you have looked in the 1st box and did not find it.
