Skill: List outcomes of a simple experiment

Explanation and Free Practice Resources

A learner identifies and names the complete set of distinct results that could occur in one simple chance experiment, such as a coin toss, a roll of a small-numbered die, or a color spinner, using words or pictures to represent the outcomes. The learner distinguishes an outcome that is possible from the result that actually occurs and lists each outcome once; calculating probabilities, comparing likelihoods quantitatively, and analyzing multi-step experiments are not included.

Detailed Explanation: List outcomes of a simple experiment

An outcome is a result that could happen in an experiment.

To list outcomes:

  1. Think about what could happen.
  2. Name each different result.
  3. Write each result only one time.

Example: Toss a coin

A coin can land in two ways:

  • heads
  • tails

So, the complete list of possible outcomes is

{heads, tails}\{\text{heads},\ \text{tails}\}

Before the toss, both heads and tails are possible outcomes. If the coin lands on heads, then heads is the result that actually occurred. The list of possible outcomes still includes both heads and tails.
