5. [[Modified problem from Ross' Probability textbook]] Servicing a particular machine requires two separate steps, with the time required for the first step being an exponentially distributed random variable with mean 0.2 hours, and the time for the second step being an independent exponentially distributed rv with mean 0.3 hours. A company has 50 machines that need to be serviced and want to set aside a budget for this that will cover the total amount of time needed to service the 50 machines with probability 0.9. That is, we want to find the time duration $\tau$ such that we are 90% sure the total time to repair the 50 machines will be $\le \tau$. Solve this problem using (a) a Normal approximation (b) a simulation.

CHALLENGE ACTIVITY 4.2.2: While loops. 401138.2627134.qx3zqy7 Jump to level 1 The program reads integers from input using a while loop. Write an expression that executes the while loop until an integer read from input is less than or equal to 0. Ex: If input is 15 23 -14, then the output is: Integer is 15 Integer is 23 Exit 1 #include <iostream> 2 using namespace std; 3 4 int main() { 5 int input; 6 7 cin >> input; 8 9 while (/* Your code goes here */) { 10 cout << "Integer is " << input << endl; 11 cin >> input; 12 } 13 14 cout << "Exit" << endl; 15 1 Check Next level 2 3
