Algebra.Com's Answer #454710 by mikeebsc(26)![]() ![]() ![]() You can put this solution on YOUR website! First, we need to see how many combinations of numbers => 10. \r \n" ); document.write( "\n" ); document.write( "6+6 or \n" ); document.write( "6+5 or \n" ); document.write( "6+4 or \n" ); document.write( "5+6 or \n" ); document.write( "5+5 or \n" ); document.write( "4+6 or\r \n" ); document.write( "\n" ); document.write( "Next we see the total number of possible outcomes from 2 dice: \n" ); document.write( "6*6=36\r \n" ); document.write( "\n" ); document.write( "Now we calculate the probability using the formula:\r \n" ); document.write( "\n" ); document.write( "number of possible outcomes in the event we are looking for/number of total possible outcomes. In this case it is 6/36 which can be reduced to 1/6. So:\r \n" ); document.write( "\n" ); document.write( "P (sum >=10)= 1/6 \n" ); document.write( " \n" ); document.write( " |
