Let X denote the number of bits in error in the next 18 transmitted bits. Answer the following questions a) Find the probability that in the next 18 transmitted bits, at least 3 transmitted in error. b) Calculate the expected value, variance and standard deviation of X. c) Find the probability that X is within 1 standard deviation of its mean value.Given an arrival process with λ = 5.0, what is the probability that an arrival occurs after t = 7 time units?Exercise 15. The probability an examinee scores above 90% on a certain standardized exam is 0.08. (a) Let X be the number of exams you must sample before you finally see ten with scores above 90%. Compute E(X) and sd(X). (b) Consider the random experiment, "Sample exams until you see ten with scores above 90%." Suppose you repeat this random experiment a trillion times and record the number of exams sampled (X values) each time. What is the (i) sample average and (ii) sample standard deviation of these trillion X values?

On a fair die, the probability that the number 6 will land face up is 1/6. A group of students wanted to investigate a claim about manipulating a fair die so that it favors one outcome. The claim states that if a fair die is put into an oven and baked at 200°F for 10 minutes, the inside of the die will begin to melt. When the die cools, the inside will be solid again, but with more weight toward the bottom. This shift in weight will cause the face that was up when the die cooled to land up more often that the other faces. The students obtained a fair die and baked it according to the preceding directions. The die cooled with the number 6 face up. After the die cooled, they rolled the die 200 times, and the number 6 landed face up 43times. Let p represent the population proportion of times the number 6 will land face up on the baked die if the die could…(a). Derive the theorem of total chance of occurrence of engineering events. (b).
