Thread: Combinations/Permutations

Hi,

This will probably be very easy for most people on this site but i have no clue.

I am trying to work out how many combinations there are for ten events each with three possible outcomes.

Example:If you take 10 football matches each having three outcomes e.g home win,draw,away win, how many possible outcomes are there for all mathches and outcomes.

I was told it might be 10 to the power of 3 but not sure and dont know how to work that out anyway.

Thankyou in advance

Make the pigeonhole principle your friend.

Hi,

Cheers for that but i dont know how to do this,could you please explain how i work out?

Thankyou

There are 3 outcomes for the first match.
3 outcomes for the second.
3 outcomes for the third.

.
3 outcomes for the tenth.

So, the number of possible outcomes = 3 * 3 * 3 * 3 * 3 * 3 * 3 * 3 * 3 * 3 = .

I hope that makes it clear.
