In how many ways can an even number of coins be selected from (6) different coins?(6) अलग-अलग सिक्कों में से सम संख्या में सिक्के चुनने के कितने तरीके हैं?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (32)(32)
An even selection means (0), (2), (4), or (6) coins. The total is (\binom{6}{0}+\binom{6}{2}+\binom{6}{4}+\binom{6}{6}=32).सम संख्या का चयन (0), (2), (4), (6) सिक्कों का होगा। कुल (\binom{6}{0}+\binom{6}{2}+\binom{6}{4}+\binom{6}{6}=32) है।
