Algebra.Com's Answer #800476 by jitendra_maths(6)![]() ![]() You can put this solution on YOUR website! given digits are 2,3,4,5,6 \n" ); document.write( " to make an even number, unit place digit must be filled by either 2, 4 or 6 \n" ); document.write( "total numbers formed by keeping 2 at unit place = 4! = 4x3x2x1 = 24 \n" ); document.write( "similarly numbers formed by keeping 4 at unit place = 24 \n" ); document.write( "and numbers formed by keeping 6 at unit place = 24 \n" ); document.write( " total even numbers = 24=24+24 = 72\r \n" ); document.write( "\n" ); document.write( "total number of ways by arranging the digits = 5! = 5x4x3x2x1 = 120\r \n" ); document.write( "\n" ); document.write( "Henc, Probability of an even number = 72/120 = 3/5 \n" ); document.write( " |
