Final answer:
The mathematics high school question is about probability, comparing the chances of two different outcomes from a set of menu options, specifically involving sirloin and prawns.
Step-by-step explanation:
The question appears to involve probabilities, commonly discussed in Mathematics at the High School grade level. The problem sets up a scenario involving sirloin and prawns, likely within the context of a probability question on a menu with multiple options. From the provided information, '82 a. yes; P(getting a pork chop) = P(not getting a chicken breast)', it appears to be an assertion of equality between probabilities. Option 'C. no' seems to indicate a disagreement with statement 'a'.
The overall goal would be to determine if the statement provided ('a.') is correct, indicating that the probability of getting a pork chop is equal to the probability of not getting a chicken breast. It's not clear how the sirloin with prawns relates directly to the probability question, as that may be part of a different or larger set of menu options within the question context. To answer this, one would typically calculate each probability based on the total number of menu options and the number of options that are pork chops or not chicken breasts, respectively.
