Algebra.Com's Answer #709101 by greenestamps(13200)![]() ![]() You can put this solution on YOUR website! This is a simple application of the fundamental counting principle. \n" ); document.write( "There are 18 choices for the first officer chosen; it doesn't matter which office it is. \n" ); document.write( "Then there are 17 choices left for the second officer chosen; then there are 16 choices left for the third officer chosen. \n" ); document.write( "So the number of ways the offices can be filled is \n" ); document.write( "18*17*16 \n" ); document.write( "Clearly, this is the permutation 18P3. However, I see too many students who think every problem like this is purely either a combination or a permutation, so I encourage you to think of it simply as an application of the fundamental counting principle. \n" ); document.write( " |
