We can omit any one of the digits  and have the possible sums

 

Omit       Sum

   1           27

   2           26

   3           25

   4           24

   5           23

   6           22

   7           21

 

So.....the probability  of a sum of 24  is   1 / 7

The probability is 1/7 not 1/6.
