Correct Answer
C. (6072)
Concept
The number of special objects can be (0), (1), or (2). The total is \(\binom{5}{0}\binom{11}{6}+\binom{5}{1}\binom{11}{5}+\binom{5}{2}\binom{11}{4}=6072\).
Why this answer is correct
The correct answer is C. (6072). The number of special objects can be (0), (1), or (2). The total is \(\binom{5}{0}\binom{11}{6}+\binom{5}{1}\binom{11}{5}+\binom{5}{2}\binom{11}{4}=6072\).
Exam Tip
विशेष वस्तुएं (0), (1) या (2) चुनी जा सकती हैं। कुल \(\binom{5}{0}\binom{11}{6}+\binom{5}{1}\binom{11}{5}+\binom{5}{2}\binom{11}{4}=6072\) है।
