In a lot of 100 microcircuits, 20 are defective. Four microcircuits are chosen at random to be tested.

Let X denote the number of tested circuits that are defective.

a. Identify the distribution of X , including any parameters, and find P(X = 2). You do not need to provide a decimal answer.

b. If appropriate (check), estimate P(X = 2) using an appropriate method.

A lot of 1000 screws contains 30 that are defective. Two are selected at random, without replacement, from the lot. Let A and B denote the events that the first and second screws are defective, respectively. (a) Prove whether or not A and B are independent events using mathematical expressions of probability.

A lot of 106 semiconductor chips contains 29 that are defective. Round your answers to four decimal places (e.g. 98.7654). a) Two are selected, at random, without replacement, from the lot. Determine the probability that the second chip selected is defective. b) Three are selected, at random, without replacement, from the lot. Determine the probability that all are defective.
