Consider a drive$-$in restaurant where carhops take orders and bring food to the car. There

are two carhops $$ Abel and Baker. Abel works a bit faster than Baker. A simplifying rule is

that Abel gets the customer if both carhops are idle. Perhaps, Able has seniority$.($The results

would be different if the decision were made at random or by any other rule so please follow

this rule$).$ Please paste corresponding Excel workbook screenshot to receive full credit $(30$
