It is true that the Seven's probability to appear in one roll is 1 in 6 (6/36 to be exact) as many of us know, but it does NOT ALWAYS roll 1 time in 6 rolls or roll 6 times in 36 rolls.

It can be seen from the above table that almost 3 out of 4 times (73.68%) in a group of 6 consecutive dice rolls
exactly 1 or 0 (zero) 7s will appear. And slightly more than 1 in 4 (26.32%) groups of 6 rolls will contain 2 or more 7s.

Sevens to Rolls Ratio (SRR) for all you precision dice setters (you know who you are) is at least 7.2 or HIGHER 43.09% of the time.
That is slightly more than 2 out of 5 for groups of 36 consecutive dice rolls. Looks like the random rollers can do just fine without trying if the goal is to have a 6.55 SRR or better!
