Toy company. A toy company manufactures a spinning game and needs to decide what probabilities are involved in the game. The plastic arrow on the spinner stops rotating to point at a color that will determine what happens next.

Knowing these probabilities will help determine how easy or difficult it is for a person to win the game and helps to determine how long the average game will last. Are each of the following probability assignments possible? Why or why not?
