Deck Size & Formula

Thanks for the information about the tool.

I can't get it to work for crypt draws. What am I doing wrong?

Looking for the chance to draw at least one if I put in 5 of a vampire in my crypt.

=HYPGEOMDIST(1,4,5,12)

It turns up 35%.

That is the probability to get exactly 1, not 1 or more. The link Lemminkainen gave provides both answers.

I've always wanted to be able to run crypt probabilities myself, so I am grateful for that link.

4 out of 12 crypt cards = 86% chance to draw in initial crypt
5 out of 12 crypt cards = 93% chance to draw in initial crypt

And never forget : if you have less than 9 copy of your star on 12 cards, the chance of drawing 0 copy of your star on the final is alway exactly 100%

V:tes has won ten years in one when people started playing 60-cards deck consistently (well I am a big fan of 70 myself but I can understand the point), don't try to make it regress 10 years by going back to 90 cards.

Well... it depends of the type of the deck that you are using...

If you use ashur tablets 60 will do the trick...

Otherwise you should playtest... must decks will fare well with 70-80 cards... if you have a rush deck that uses a lot of cards in each action you might end up without a library...
