You randomly select two letters from eight tiles that spell G.E.O.M.E.T.R.Y.\r\n" ); document.write( "replacing the first before you select the second,what is the probability that\r\n" ); document.write( "you will select two E's\r\n" ); document.write( "\r\n" ); document.write( "P(selecting E the 1st time) = 2 out of 8 = 2/8 = 1/4\r\n" ); document.write( "P(selecting E the 2nd time) = 2 out of 8 = 2/8 = 1/4\r\n" ); document.write( "\r\n" ); document.write( "Since we are replacing the letter chosen before choosing the second letter,\r\n" ); document.write( "the events are independent and we can muiltiply the probabilities:\r\n" ); document.write( "\r\n" ); document.write( "P(selecting E 1st time AND selecting E 2nd time) = \r\n" ); document.write( "\r\n" ); document.write( "P(selecting E 1st time) × P(selecting E 2nd time) = (1/4)×(1/4) = 1/16\r\n" ); document.write( "\r\n" ); document.write( "Edwin\r\n" ); document.write( "AnlytcPhil@aol.com\n" ); document.write( " |
