Saturday Night Contest - Guess Again

math.

Well, its (55*55)/2 to account for the doubles. Dividing by two will kill the unique issue. Or should.

-ThrallMind

not true.

the total number of events is just 55*54/2 + 55. think about it. make two sets. where we have two different cards and the same cards.

different cards:
55 choose 2.
55*54/2

same cards:
we have 55 pairs.

stop playing with cards and study math!
i'm in stat right now. :D
 
2x Ace of Spades

2x Ace of Hearts

2x Ace of Diamonds
2x 6 of Diamonds

2x Ace of Clubs
2x 2 of Clubs

2x Double Backers

2x Jokers

2x Any of the Jacks

And also... The ad cards have no back. They are the ad on both sides.

Actually, (55*54) + 55 should do it.

Omg! It seems that both my first and second guesses had been taken up by the others. I'm wondering if I should look through all of the posts, compile them into a list, and thoroughly analyse the guesses, and come up with a very educated guess using the process of elimination? By but the time I had done so, some others might just have had their wild guesses right! So I might just as well have a wild guess here... Lol!

Wow. ThrallMind. You really are putting a lot of thought into this very simple contest. =)

i tell you sir, it does not. haha.

combinations (order does not matter a.k.a king of spades-ace of spades is equal to ace of spades-king of spades)-

nCx (n choose x)
n!/(x!*(n-x)!)
so (55*54*...)/((53*52*51..)(2*1))

permutations (order does matter a.k.a king of spades-ace of spades is NOT equal to ace of spades-king of spades)

nPx
simply. n!/(n-x)!


i stand by 55*54/2 + 55 = 1540 i think
