21 is average of 3 cards

Can 6 be taken as a mean average of the ace, ie midway between 1 and 13?

If so, then 2 3 4 5 6 7 8 9 10 10 10 10 + 6 = 91 for the value of deck

91 divided by 13 cards

=

7.

Is 7 the average value likely to arise?

Is 3 cards on average more likely to result in 21 anyway?

thanks for looking!

Since it will more often be used as an 11-count card than a 1-count, I would think that the mean would be more like 8. If it's initially dealt with a 9, 10, J, Q, or K, it will be counted as 11; with a 7 or 8, it will almost always be counted as 11; with another Ace, it will be counted as 11 (even if it's split and dealt a deuce). And even if it's dealt as part of A2-A6, it will often eventually be counted as 11 rather than 1.
