Therefore, the answer is 6. This can also be calculated another way: since we know we rolled 2 dice, the total sum of the front and back faces of the dice must be 14 (7x2). If we then subtract the sum of the rolled values (2+6=8) from our total sum, we get the correct final answer (14-8=6)!</w:t></w:r></w:p></w:body></w:document>"},{"partUri":"/matlab/output.xml","contentType":"text/xml","content":"<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"no\" ?><embeddedOutputs><metaData><evaluationState>manual</evaluationState><layoutState>code</layoutState><outputStatus>ready</outputStatus></metaData><outputArray type=\"array\"/><regionArray type=\"array\"/></embeddedOutputs>"}]}
