Re: Crypto Stamps- New Collectable Blockchain postage stamps
Btw: Your chances for one or more red stamps is 40.5% if you ordered 50
Yes indeed, i got the same 1-(1-1500/150000)^50=0,405
That being said, the exact calculation involves the hypergeometric distribution. However i agree that,
in this case, the binomial distribution can be used instead.
Best regards
The only thing i am worried about this calculation is if its truly a random selection that they are offering to people.
I hope so too...but then where humans are involved
Jup, I am very suspicious of that too.
Today my first order of 25 stamps arrived...
Very poorly results.
- 18 black
- 4 green
- 3 blue
I might just be very very unlucky... but chances are, some orders might be tempered with by some of the employees doing the packaging and are actually prescanned (mostly for reds but possibly also for yellow ones).
I think the color check code area should've been covered as well with a scratch off to prevent this from happening.
The Austrian post office should be made aware of these issues to prevent them hopefully from happening again
