Algebra.Com's Answer #796120 by Boreal(15235)![]() ![]() You can put this solution on YOUR website! 5 ways to choose the first and then 4 ways to choose the second. \n" ); document.write( "That is 20 total ways \n" ); document.write( "four of them add to 6: they are 1-5 and 5-1 and 2-4 and 4-2. \n" ); document.write( "The answer is 20% or 1/5. \n" ); document.write( "- \n" ); document.write( "if 1, (20% probability) then the other choices are 2-3-4-5 with equal probability of 25%. \n" ); document.write( "So probability is 5% with each pairing and 1-5 sums to 6. \n" ); document.write( "same for 2 and 2-4 with 5% \n" ); document.write( "0 probability if first piece is 3. \n" ); document.write( "the 5% probability with 4 and then 2 \n" ); document.write( "and with 5 and then 1.\r \n" ); document.write( "\n" ); document.write( "Overall, it is a 20% probability. \n" ); document.write( " |
