Consider a system consisting of three independent components. Suppose the lifetimes of these components follow an Exponential distribution with mean 300 hours, 410 hours, and 600 hours, respectively. a. Suppose that the system works only if all three components are functional (e.g., series connection). Find the probability that the system still works after 550 hours. That is, find the probability that all three components still work after 550 hours. Round your answer to 4 decimal places. "Hint": P(X1 > 550 hours AND X2 > 550 hours AND X3 > 550 hours)

A student's course grade is based on one midterm that counts as 1010% of his final grade, one class project that counts as 1010% of his final grade, a set of homework assignments that counts as 4040% of his final grade, and a final exam that counts as 4040% of his final grade. His midterm score is 6666, his project score is 8484, his homework score is 8484, and his final exam score is 6767. What is his overall final score? What letter grade did he earn (A, B, C, D, or F)? Assume that a mean of 90 or above is an A, a mean of at least 80 but less than 90 is a B, and so on.
