Algebra.Com's Answer #327364 by Theo(13342)![]() ![]() You can put this solution on YOUR website! i believe the combination formula will give you your answer. \n" ); document.write( "you have 5 red flowers, 3 pink flowers, and 2 white flowers. \n" ); document.write( "i believe you answer will be given by the following formula: \n" ); document.write( "number of possible combination is equal to: \n" ); document.write( "n!/(x!*y!*z!) \n" ); document.write( "n is the total number of flowers \n" ); document.write( "x is the number of red flowers \n" ); document.write( "y is the number of pink flowers \n" ); document.write( "z is the number of white flowers \n" ); document.write( "the actual numbers replace the letters to get: \n" ); document.write( "10!/(5!*3!*2!) which is equal to 2520 possible arrangements. \n" ); document.write( "this is hard to see because there are so many combinations. \n" ); document.write( "it's easier to see when there are fewer. \n" ); document.write( "assume you had 5 flowers in total. \n" ); document.write( "2 are red and 3 are blue \n" ); document.write( "the number of ways you can arrange them should be 5!/(2!*3!) = 10 \n" ); document.write( "if we let a equal to the red flowers and b equal the blue flowers, then we can model the arrangements are shown below: \n" ); document.write( "aa is in the first 2 positions \n" ); document.write( "aabbb \n" ); document.write( "ab is in the first 2 positions \n" ); document.write( "ababb \n" ); document.write( "abbab \n" ); document.write( "abbba \n" ); document.write( "ba is in the first 2 positions \n" ); document.write( "baabb \n" ); document.write( "babab \n" ); document.write( "babba \n" ); document.write( "bb is in the first 2 positions \n" ); document.write( "bbaab \n" ); document.write( "bbaba \n" ); document.write( "bbbaa \n" ); document.write( "total possible combinations is 10. \n" ); document.write( "same concept works with the bigger numbers. \n" ); document.write( "10! / (5!*3!*2!) = 2520 possible arrangements. \n" ); document.write( " |
