There are different ways to design a queue. Select the appropriate queue or waiting line design for each of the following examples: Example I: Hal waits in line at an eatery to place his carryout order. Assume there is only one cash register and one employee designated and trained to take customers' carryout orders. Example II: Joy is in line at an NBA game, eagerly awaiting her turn to purchase hotdogs and beverages. Upon reaching the front of the line, she can make her purchase from any of the three employees currently staffing the concessions area at the stadium. Example III: Sophie, a freshman residing in the dorms, is currently engaged in the task of getting something to eat at Yogurt Extreme. However, she is not a big fan of adding too many toppings to her yogurt. First, she has to choose one yogurt from several yogurt options, and then, in the second step, she selects one topping from many topping choices
