How this game is played you pick out of the number 10. You pick the number I think of you get 10 points. You get it wrong you get no points. Also for a bonus if you get the number next to mine you get 5 points. For example if I guess the number 4 and you say 3 you get 5 points. Who gets most points at the end of the game wins.

This is a bad idea...what's to stop someone from changing the numbers until someone they like wins?

I'll ask an easy question instead!
A prime number, which when multiplied by 1.4, makes another prime number (both under 10).

Congratulations!

16 divided by 2?
Wait, that's too easy...

I presume that the !'s are factorials.

For those of you who don't know, a factorial is when you multiply a number by...
Well, the above would be:
(8*7*6*5*4*3*2*1)/((4*3*2*1)*(3*2*1)
40,320/(24*6).
40,320/144
280

So 8!/4!3! = 280.
...That's...not between 1 and 10.

good job!

I never set constraints for my problem.

How many ways can you have 5 yachts get first, second, and third place. A yacht cannot get more than one place, and only three can place.
