For this lab assignment, the experiment is to roll a fair die twice. If the random variable x represents the sum of the numbers rolled, find the probability distribution for this random variable.
\n" ); document.write( "----
\n" ); document.write( "Draw the sample space.
\n" ); document.write( "Draw a 6x6 square.
\n" ); document.write( "Put 1,2,3,4,5,6
\n" ); document.write( "along the left edge and along the top.
\n" ); document.write( "Put the sum of the row and the column numbers for each box in the square.
\n" ); document.write( "You should see something like the following:
\n" ); document.write( "2,3,4,5,6,7
\n" ); document.write( "3,4,5,6,7,8
\n" ); document.write( "4,5,6,7,8,9
\n" ); document.write( "....
\n" ); document.write( "....
\n" ); document.write( "7,8,9,10,11,12
\n" ); document.write( "=========================
\n" ); document.write( "Note that there are 36 sum entries
\n" ); document.write( "P(2) = 1/36
\n" ); document.write( "P(3) = 2/36
\n" ); document.write( "P(4) = 3/36
\n" ); document.write( "....
\n" ); document.write( "P(11) = 2/36
\n" ); document.write( "P(12) = 1/36
\n" ); document.write( "===================
\n" ); document.write( "That is the probability distribution.
\n" ); document.write( "==========================================
