Outcomes and sample spaces

Outcomes and sample spaces describe the possible results of a random process.

Mei flips a coin twice in a card game with her brother, and both flips land heads. What other results could those two flips have given her?

What you'll learn5 ideas
  • An outcome is one possible complete result, like heads on one coin flip.
  • When you record a first and a second result, heads then tails is a different outcome from tails then heads.
  • The sample space is the full list of every possible outcome, like heads and tails for one coin flip.
  • Each different result goes on the list only once, no matter how many tokens lead to it.
  • A sample space lists what can happen, not just what already happened.
