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.
