\n" ); document.write( "Problem 1\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "I'm assuming the four sides of the tetrahedral dice are labeled 1,2,3,4
\n" ); document.write( "There are two ways to sum to 5 and they are:
\n" ); document.write( "1+4 = 5
\n" ); document.write( "4+1 = 5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "This is out of 4*4 = 16 ways to throw the two four-sided dice.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So 2/16 = 1/8 is the probability we want.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Answer: 1/8\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "=============================================================\r
\n" ); document.write( "\n" ); document.write( "Problem 2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Here are the ways to get a difference of 1, where the first die is larger than the second and I'm subtracting in the format first-second
\n" ); document.write( "4-3 = 1
\n" ); document.write( "3-2 = 1
\n" ); document.write( "2-1 = 1\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now let's assume that the second die is the larger of the pair and we subtract using absolute value so we get a positive result
\n" ); document.write( "|3-4| = 1
\n" ); document.write( "|2-3| = 1
\n" ); document.write( "|1-2| = 1
\n" ); document.write( "again I'm subtracting in the format first-second, but the absolute value bars ensure the result is never negative.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "We have 6 such ways to get the two dice to be separated by 1. This is out of the 4*4 = 16 ways to throw the two dice.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "6/16 = 3/8\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Answer: 3/8\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "=============================================================\r
\n" ); document.write( "\n" ); document.write( "Problem 3\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Here are all of the ways the two dice could multiply to 4
\n" ); document.write( "1*4 = 4
\n" ); document.write( "2*2 = 4
\n" ); document.write( "4*1 = 4
\n" ); document.write( "There are 3 ways to get what we want out of 16 ways to throw the dice.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Answer: 3/16
