Eight people, all of different heights, are to be seated in a row. Neither the tallest person nor the shortest person is seated at either end of the row.
\n" ); document.write( "a.) how many different seating arrangements are possible?
\n" ); document.write( "----
\n" ); document.write( "# of ways to succeed:
\n" ); document.write( "1st position: 6 ways
\n" ); document.write( "8th position: 5 ways
\n" ); document.write( "2nd thru 7th positions: 6! ways
\n" ); document.write( "Total ways: 30*6! = 21600
\n" ); document.write( "--------------------------------------
\n" ); document.write( "b.) what is the probability that the tallest and shortest people are sitting next to each other?
\n" ); document.write( "# of ways to succeed:
\n" ); document.write( "1st position: 6 ways
\n" ); document.write( "8th position: 5 ways
\n" ); document.write( "2nd thru 7th positions: 2*5! = 240 (treat the 2 persons as one)
\n" ); document.write( "Ans: Probability = (6*5*240)/21600 = 1/3
