| Algebra.Com's Answer #310214 by stanbon(75887)      You can put this solution on YOUR website! An ordinary fair die is a cube with numbers 1 through 6. The die is rolled twice in succession, and the face value of the two rolls are added together. This sum is recorded as the outcome of a single trial of a random experiment. Compute the probability of the following events: \n" ); document.write( "Event A: The sum is greater than 7. \n" ); document.write( "sum = 8: 2/6;3/5;4/4;5/3;6/2 \n" ); document.write( "sum = 9: 3/6;4/5;5/4;6/3 \n" ); document.write( "sum =10: 4/6;5/5;6/4 \n" ); document.write( "sum =11: 5/6;6/6 \n" ); document.write( "sum =12; 6/6 \n" ); document.write( "Total number of these is 5+4+3+2+1 = 15 \n" ); document.write( "P(sum greater than 7) = 15/36 \n" ); document.write( "======================================= \n" ); document.write( "Event B: The sum is divisible by 5 or 6 (or both). \n" ); document.write( "I'll leave this to you. \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "========== \n" ); document.write( " \n" ); document.write( " |
