Similarly since we want "not a 3", we need to consider the complement of B:. Finally, we notice the key word "and". Thus, we are asked to find:. Consider the following sentence, "If you randomly select a person, find the probability that the person is older than 8 or is both younger than 6 and is not younger than 3. First, let A be the set of people older than 8, B be the set of people younger than 6, and C be the set of people younger than 3.
The clearest way to display this union is on a number line. The number line below displays the answer:. Suppose that we pick a person at random and are interested in finding the probability that the person's birth month came after July and did not come after September. Write this event using set notation. Learning Outcomes Find the union of two sets.
