If (A={1,2,3,4}) and (B={a,b}), how many onto functions are there from (A) to (B)?यदि (A={1,2,3,4}) और (B={a,b}), तो (A) से (B) में आच्छादक फलनों की संख्या कितनी है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (14)(14)
Step 1: Total functions are (2^4=16). Step 2: There are two non-onto functions, where all elements go only to (a) or only to (b). Step 3: Therefore onto functions are (16-2=14).चरण 1: कुल फलन (2^4=16) होंगे। चरण 2: आच्छादक न होने वाले फलन दो हैं, जिनमें सभी अवयव केवल (a) या केवल (b) पर जाते हैं। चरण 3: इसलिए आच्छादक फलन (16-2=14) होंगे।
