Problem 2. Consider n flips of a coin. A run is a sequence of consecutive tosses with the same result. For k<n, let Ek be the event that a run is completed at time k; this means that the results of the kth and (k1)st flips are different. For example, if 10 and the outcomes of the first 10 flips are HHHTTHHTTH then runs are completed at times 3,5,7,9 (a) Show that if the coin is fair, then the events...
using Matlab: A drug administered to a patient produces a concentration in the bloodstream given by c(t)=Ate^(-t/3) milligrams per milliliter, t hours after A units have been injected. The maximum safe concentration is 1.00 mg/mL. What amount should be injected to reach this maximum safe concentration, and when does this maximum occur? (Use calculus to find the time when a maximum occurs. Then set c(tmax) = 1 to solve for A.) An additional amount of this drug is to be...
