Becase of the multiple modes by which a total can be obtained, this doesn't
lend itself to a simple expression (unlike the 2-dice problem). If I wanted
to calculate the results in a hurry without thinking about the combinatorics,
then I would use helper columns as follows:

In C1:F1 enter the number 1
In C2 enter the formula =IF(SUM(D2:$F2)=COUNT(D2:$F2),IF(C1=6,1,C1+1),C1)
Copy C2 and Paste into D2:E2
In F2 enter the formula =IF(F1=6,1,F1+1)
Copy C2:F2 and Paste into C3:F1296
In G2 enter the formula =SUM(C1:F1)
Copy G2 and Paste in to G3:G1296

Now the probability of getting a total of n across the 4 dice can be
calculated as
=COUNTIF($G$1:$G1296,n)/6^4
