Plz give me a help to find the answer for the following simulation problem

A Process planner is working on plans for producing a new detergent. She
wishes to simulate a row-material demand in order to plan for adequate materials handling and storage facilities. On the basis of usage for a similar product introduced previously, she has developed a frequency distribution of demand in tons per day for a 2 month period. Use this data to simulate the raw material usage, requirement for 7 periods (days).
Demand pattern for two month period:
Demand, X (tons/day) 10 11 12 13 14 15
Frequency (no. days) 6 18 15 12 6 3
(Use Random Number table)
