Question 695912
<pre>

Below are all 36 possible rolls.  The 5 of them that total 8
are in red.  So we should expect the {{{5/36}}}ths of the
rolls should total 8.  So the answer is {{{5/36}}}ths of 450,
That's 62.5 rolls.  Of course you will never expect to ever
have "half a roll". What that means is if you rolled them
490 times each day for a year, you would expect the average
number of rolls totaling 8 to be 62.5.
