Final answer:
Without the complete question it's impossible to provide a full answer, but it appears to involve set theory, in which we would analyze the number of students engaged in musical instruments, sports, or both.
Step-by-step explanation:
The student's query appears to be related to the field of mathematics, specifically the area of set theory or venn diagrams. Unfortunately, the question seems to be incomplete, as it mentions 21 students play "b" but does not finish the statement.
To answer the question thoroughly, we would need to know how many students play a musical instrument, how many students play a sport, and perhaps how many do both. With complete information, we could use the principles of set theory to find out more about the class, such as the number of students who play only a musical instrument, only a sport, or neither.
The complete question is: Jorge Asked Each Of The 24 Students In His Class If They Play A Musical Instrument. He Also Asked Each Student If They Play A Sport. He also asked each student if they play a support.
