Algebra.Com's Answer #641805 by robertb(5830)![]() ![]() You can put this solution on YOUR website! Now P(P) = probability that “the sum shown is 8” = 5/36, and \n" ); document.write( "P(Q) = probability that “the two dice show the same number” = 6/36 = 1/6.\r \n" ); document.write( "\n" ); document.write( "==>P(P|Q) = P(P∩Q)/P(Q) = \n" ); document.write( "Also, P(Q|P) = P(P∩Q)/P(P) = \n" ); document.write( "\n" ); document.write( "Note: P(P∩Q) = 1/36 because only the outcome (4,4) will satisfy the event P∩Q. \n" ); document.write( " |
