If you have 5 football matches with 3 outcomes win lose or draw how many different combinations are there?

3 + 3 + 3 + 3 + 3 = 15 total possible outcomes.

You can 'prove' this by laying out a table of possibles where a user might tick the result of each game.....

Match....1....2....3....4....5

Win......._...._...._...._...._

Lose......_...._...._...._...._

Draw....._...._...._...._...._
