1-57.

Joyce’s dad packs her lunch and always packs a yogurt. Joyce knows that there are five yogurts in the refrigerator: one raspberry, two strawberry, one blueberry, and one vanilla. Her dad usually reaches into the refrigerator and randomly grabs a yogurt. Homework Help ✎

  1. Which flavor is she most likely to have in her lunch today?

    The chances of picking a particular flavor of yogurt are greater when there is more than one container of that flavor in the refrigerator. Can you tell if any one yogurt flavor has a higher probability, or chance, of getting picked by Joyce's dad?

    Strawberry is the flavor most likely to be chosen because there are two containers of this flavor in the refrigerator.

  2. What are her chances of finding a vanilla yogurt in her lunch bag?

    The probability of something happening can be determined by placing the number of times a ''successful outcome'' is possible over the total number of possible outcomes.

    In this case, the ideal outcome would be picking vanilla yogurt. This is only possible one time and there are five possible yogurt choices, or ''outcomes.'' Can you find the probability of picking vanilla?
