If (f:A\to B) is bijective and (|A|=7), what is the value of (|B|)?यदि (f:A\to B) द्वैक है और (|A|=7), तो (|B|) का मान क्या होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (7)(7)
Step 1: A bijective function is both one-one and onto. Step 2: For finite sets, a bijection is possible only when both sets have the same number of elements. Step 3: Therefore (|B|=|A|=7).चरण 1: द्वैक फलन एकैकी और आच्छादक दोनों होता है। चरण 2: सीमित समुच्चयों में द्वैक फलन तभी संभव है जब दोनों समुच्चयों में बराबर अवयव हों। चरण 3: इसलिए (|B|=|A|=7) होगा।
