**Example 4**

The American Association of Teachers found that 42% of public school teachers have a graduate degree and 61% of public school teachers have multiple subject teaching credentials. Furthermore, they found that 79% of public school teachers do not have a graduate degree or do not have a multiple-subject teaching credential. A public school teacher is selected at random.
