parlay combinations

[AdamD7]

If you had 20 teams squaring off against each other and covered every possible combination with parlays, how many combinations would be in that 10 team parlay ? Just out of curiousity.......

Anyone know how to figure that one out?

 

[AdamD7]

......and this is just for knowledge only. I'm not gonna actually try to place a bet on on combinations for like $10,000 or anything!

It's pretty much to settle an argument at work, but none of us are smart enough to figure out the math on this.

10x9 = 90

1X2= 2

90 divided by 2 = 45 combinations.

2^10=1024

1024 combinations

lol, if there were only 45 combinations for a 10 team parlay, everyone would be rich.

there's actually 1024 different combinations with a .00098 chance of winning

he didn't ask about one 10 teamer.

He asked how many TWO teamers.

45.

No, he asked about one 10 teamer.

how many combinations would be in that 10 team parlay ?

Guess I gave him the correct information for a question he did not ask.
Here's some more he might find useful.

45 two-team parlays in 10 games.


120 three team parlays in 10 games.


210 four-team parlays in 10 games.
