Need the solution asap thanks.

Q3 (30 points): Remember the florist example and our discussions on the solution. Actually, you may reach to the video of that synchronous lecture over webonline. Then, solve the below problem. A florist stocks 18 dozens of roses at the beginning of each week. On the average it sells 3 dozens a day. Actual demand follows a Poisson distribution. Whenever the stock level reaches 5 dozens or below, a new order of 18 new dozens is placed for delivery at the beginning of the following week. Because of the nature of the item, all roses left at the end of the week are disposed. Determine a. (5 points) the probability of placing an order until (including) Wednesday. b. (5 points) the probability of placing an order on Wednesday (not before). C. (10 points) the probability of placing an order in any one day of the week. d. (10 points) the average number of dozens of roses that will be discarded at the end of the week. Q3 (30 points): Remember the florist example and our discussions on the solution.
