Save A Question 4 15 points Consider a bank with two tellers. An average of 2 customers per hour arrive at the bank and wait in a single line for an idle teller. The average time it take to serve a customer is a triangular (x1 = 1, y1 = 0), (x2 = 5, y2 = h) Assume that inter arrival times and service times are exponential. Use the method of Inverse Transformation to develop the arrival equation? O a. IT =-0.5*Ln(R) O b.IT = -0.5*Ln(1-R) O c. IT = -0.5*Log(1-R) O d.IT = -2*Ln(1-R)
