Add volunteers and staff.
Volunteers are people who come in for a few hours a day to explain the exhibits to the visitors.
They stay for an average of three hours with a deviation of one hour, normally distributed. There are four staff members who arrive first thing in the morning. You will also need SimPkg.st . Your simulation should keep track of the number of people in the museum at each time interval, where the number of people includes staff, volunteers, and visitors. Have your simulation be able to output the maximum number of people at any time.
