an,t = an_M(ft(385 — n + t))/((n — 0(417 — n)) (7)
an,t = On.i-i((ft -t + 1)(33 - t))/(£(384 - n + t)). (8)
Let N' be the total number of cards which are not used during play, i.e., N' is the sum of the numbers of unseen burned cards and the cards left in the shoe when the house decides to shuffle. Then 416—N' cards are actually dealt. Thus the number nf, of cards which as yet have not been used at some instant during play of a shoe, ranges from 416 to JV' + l.
