Final answer:
Without an explicit listing of the weight of Sliced Pork Belly, we use a 3 oz pork chop as a reference, estimating a slice of pork belly to potentially weigh slightly less. Probabilities regarding being served specific weights of meat require information about the total number and distribution of meat pieces in the restaurant.
Step-by-step explanation:
To determine the weight or count of Sliced Pork Belly, we need to consider similar items as a reference since sliced pork belly is not explicitly listed. However, looking at the related options given, we have a pork chop weighing 3 oz. One could reasonably assume that a single slice of pork belly might weigh slightly less since it is usually thinner than a full pork chop. But without the exact weight/count provided, we can use 3 oz as a rough estimate for a thick slice of pork belly.
For the exercise provided, if a local restaurant menu lists the weights of pork chops and chicken breasts and your server will randomly select one piece of meat to serve you, the probability of not getting a chicken breast and getting an 18-oz. pork chop would require information on the total number of available chicken breasts and pork chops, as well as how many of those pork chops are 18 oz. Similarly, to calculate the probability of getting a piece of meat that is not 21 oz, we would need the total number of meat pieces that are not 21 oz in comparison to the total number of meat pieces available.
