Let's assume that each of the persons in the line has a number ... including Jack and Jill.
\n" ); document.write( "Therefore, the pool of numbers is 100. Also assume that the persons in the line have the
\n" ); document.write( "number that represents their position in the line. (Jack's number would be 28 and Jill's 68.)
\n" ); document.write( ".
\n" ); document.write( "How many of those 100 numbers are between 28 and 68? Start with 29 and end with 67. There are 39
\n" ); document.write( "numbers between 28 and 68. So if you draw a number at random from a pool of 100 numbers you
\n" ); document.write( "have 39 chances that the number you pick is in the range of 29 through 67. Therefore,
\n" ); document.write( "the probability of picking one of those numbers is $\"39%2F100+=+0.39\"$
\n" ); document.write( ".
