A particularly long traffic light on your morning commute is green 40% of the time that you approach it. Assume that each morning represents an independent trial. Let denote the number of mornings the light is green. a) Over 10 mornings, what is the probability that the light is green on exactly 4 days? Round your answer to three decimal places (e.g. 98.765) b) Over 20 mornings, what is the probability that the light is green on exactly 8 days?...

A batch of 536 containers for frozen orange juice contains 6 that are defective. Two are selected, at random, without replacement from the batch. a) What is the probability that the second one selected is defective given that the first one was defective? Round your answer to five decimal places (e.g. 98.76543). b) What is the probability that both are defective? Round your answer to seven decimal places (e.g. 98.7654321). c) What is the probability that both are acceptable? Round...

A computer system uses passwords that contain exactly 3 characters, and each character is one of the 26 lowercase letters (a-z) or 26 uppercase letters (A-Z) or 10 integers (0-9). Let Ω denote the set of all possible passwords, and let and denote the events that consist of passwords with only letters or only integers, respectively Suppose that all passwords in 2 are equally likely. Determine the following probabilities. Round your answers to three decimal places (e.g. 98.765). (c) The...
