Lesson: Applied Arithmetic - 28

Probability Of Combinations

[Page 28 of 36]

Some probability questions involve finding the probability of certain combinations of outcomes after multiple events take place. These questions differ from the previous example in that a specific event does not need to have a specific outcome, but the outcomes as a collective must exhibit certain traits.

For example:

If a fair coin is thrown twice, what is the probability of throwing one head and one tail?

To determine multiple-event probability where individual events can have different outcomes:

  • Find the total number of possible outcomes by determining the number of possible outcomes for each individual event and multiplying these numbers together.
  • Find the number of desired outcomes by listing out the possibilities.

Now let's solve the above example.
