Algebra.Com's Answer #735529 by greenestamps(13215)    You can put this solution on YOUR website! \n" ); document.write( "Contractor C is the least likely to win. So let x be the probability that C wins. \n" ); document.write( "Then \"contractor B is 7 times MORE likely to win than contractor C\" means the probability that contractor B wins is x + 7(x) = 8x. \n" ); document.write( "Then \"contractor A is 4 times MORE likely to win than contractor B\" means the probability that contractor A wins is 8x + 4(8x) = 40x. \n" ); document.write( "The sum of the probabilities must be equal to 1: \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "The probability that C wins is x = 1/49. \n" ); document.write( "The probability that B wins is 8x = 8/49. \n" ); document.write( "The probability that A wins is 40x = 40/49. \n" ); document.write( "  |
