At an urgent care facility, patients arrive at an average rate of one patient every 6 minutes (that is λ-6). Assume that the duration between arrivals is exponentially distributed 1) (a) Find the probability that the time between two successive visits to the urgent care fa- cility is less than 4 minutes. (b) Find the 75th percentile. That is, determine To.75 (c) Find the probability that more than 6 patients arrive during a half-hour period.
