Algebra.Com's Answer #598579 by xxLaurax(5)![]() ![]() You can put this solution on YOUR website! You can solve this two ways.\r \n" ); document.write( "\n" ); document.write( "Permutations is when order does matter. \n" ); document.write( "So you have a block size of 30 and 3 groups. You ONLY want three NOT 30 so it will be 30*29*28 = 24,360.\r \n" ); document.write( "\n" ); document.write( "OR\r \n" ); document.write( "\n" ); document.write( "If you have a graphing calculator, you click MATH, move to the category that says PROB stands for probability. Then click on nPr which stands for permutation. n stands for how many blocks you have in this case and r stands for how many groups you only want. It would look like 30P3 = 24,360. \n" ); document.write( " |
