I accept that the result was not Gary's intention. However, if packs were being picked randomly, the odds of my not getting one with a puzzle piece are astronomical. The likelihood is packs were being opened to build puzzles and somehow, unintentionally, I was given packs that were left over from this process. No other explanation is plausible.
I agree. Assuming 5 of the 24 packs were stiff and had puzzle pieces, then once the sketch card pack is taken out of the equation, the odds of a particular pack not having a sketch card are 18 in 23. Raising 18/23 to the 24th power, assuming a random pull from a very large population of packs, results in the probability of no puzzle packs in a batch of 24 being about .003 or 3 in 1,000. Assuming 6 of the 24 packs were stiff and had puzzle pieces, the odds would be .0007, or 7 in 10,000.
However, that being said (and calculated), I continue to recommend contacting Gary and the immediate issue will be taken care of!
