Algebra.Com's Answer #292846 by scott8148(6628)![]() ![]() You can put this solution on YOUR website! this is a binomial probability ___ you either get a six or not a six\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "P of 6 ___ 1/6 ___ call this S\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "P of not 6 ___ 5/6 ___ call this N\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "P of 10 sixes in 60 tries ___ 60C10 * (S^10) * (N^50)\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "use this technique to find the probability of 8 and the probability of 9 \n" ); document.write( " |
