@Zooko: Well, I thought he had asked about the probability to encounter that particular pattern again, which is of course independent of past experiments...

@thinktank: BTW, the probability to observe exactly the same sequence of mystics (or pattern) is
((1/4*1/4*1/4) *1)^5 * ((1/4 * 1/4 * 1/4) *3)^1 = something small
The 3 is there because there are three types of a1e2 mystics (a either in the first, second or third pick obtained).
