Three spinners are shown at right. If each spinner is randomly spun and if spinners #2 and #3 are each equally divided, find the following probabilities.

Three spinners. Spinner # 1 has two sections. Three-fourths section is labeled A and one-fourth section is labeled B. Spinner # 2 is divided into two equal sections, labeled C and D. Spinner #3 is divided into 3 equal sections, labeled E, F, and G.

Hint:

Use a tree diagram to illustrate all possible combinations that can occur if each spinner is spun once.
Refer to the Math Notes box in Lesson 4.2.3 for information on tree diagrams.

$P(\text{spinning } A, C, \text{ and } E)$
$P(\text{spinning at least one vowel})$
Answer (b):
