Algebra.Com's Answer #586138 by Edwin McCravy(20060)![]() ![]() You can put this solution on YOUR website! \r\n" ); document.write( "Probability is what percent of the time something will happen on the average.\r\n" ); document.write( "Propability could be expressed as a percent of the time, a decimal, or a\r\n" ); document.write( "fraction of the time. It's \"unit\" is always of the time.\r\n" ); document.write( "\r\n" ); document.write( "The coin is heavier on one side than the other and it lands heads only 35% of\r\n" ); document.write( "the time and it lands tails the other 65% of the time, on the average.\r\n" ); document.write( "\r\n" ); document.write( "You will flip a head only 35% of the time.\r\n" ); document.write( "\r\n" ); document.write( "Then 35% of the times that you flipped a head first, you'll flip a head a\r\n" ); document.write( "second time. So that's 35% of 35% of the time.\r\n" ); document.write( "\r\n" ); document.write( "Answer: 35% of 35% of the time. = (0.35)(0.35) = 0.1225 or only\n" ); document.write( " |
