Algebra.Com's Answer #510270 by swincher4391(1107) You can put this solution on YOUR website! I apologize for last time. I made a slight error. \r \n" ); document.write( "\n" ); document.write( "P[multiple of 3] = 1/3 = 12/36 \n" ); document.write( "P[sum of 8] = 5/36\r \n" ); document.write( "\n" ); document.write( "However as I said last time (3,5) is not the only roll that satisfies both, we also have (6,2). This means we need to take in account the 2 cases out of 36 where both events take place. \r \n" ); document.write( "\n" ); document.write( "So we calculate 12/36 + 5/36 - 2/36 = 5/12 which is our answer. \n" ); document.write( " |
