In Response To: Average number of rolls to roll 66 (Raj Jansari)

The average number of rolls for an event to occur is very straightforward. Just take the reciprocal. For examples, Avg number of flips to toss a head = 2. Avg number of rolls to get a 66 = 36, Avg number of rolls to get a 44, 55 or 66= 12.
