I need solution and Matlab code. And also simulation result

1. Assume that telephone calls to a stock broker in an interval from 0 to t have a Poisson probablety distribution function and that they made randomly and independently in time with an average rate of 2 per second. a. Determine the probably using Matlab that exactly k calls are made in an interval of f long. Given t= 10/) and k = 1,2....8 b. Repeat a. if t =5/2. c. What are the significant between a. and b. ?
