Algebra.Com's Answer #729733 by Theo(13342)![]() ![]() You can put this solution on YOUR website! the stock price can vary between 10 and 20. \n" ); document.write( "that's 11 possibilities.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "the probability of any one of those events occurring is 1/11. \n" ); document.write( "the probability of any one of those events not occurring is 10/11.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "the probability that it could be 10 is therefore 1/11. \n" ); document.write( "the probability that it could be 11 is therefore 1/11. \n" ); document.write( "the probability that it could be 12 is therefore 1/11.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "the probability that it could be 10 or 11 or 12 is therefore 3/11.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "the probability that it could be 13 through 20 is therefore 8/11.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "since 13 through 20 is greater than 12, then the theoretical probability of making money on the stock in 6 months is 8/11.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "that's what i think.\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
