Algebra.Com's Answer #190385 by drk(1908)![]() ![]() ![]() You can put this solution on YOUR website! For part (1) There are 6 digits and 6 slots, so we have 6! or 720 ways. \n" ); document.write( "-- \n" ); document.write( "For part (2) to be divisible by 6, the number must be divisible by 2 and 3. \n" ); document.write( "It turns out that every 6 digit number we create will be a multiple of 3. \n" ); document.write( "Look at our even numbers. We can choose 2 of the 6 or 6c2 = 15. SO the answer to part (2) is 15 ways. \n" ); document.write( " |
