The 10x10 represents your family's garden.  You helped plant the garden and decided to put one surprise sunflower in the garden.
If you planted 25 of the same gardens (with a randomly planted sunflower), how often would you expect the sunflower to be planted in the green bean section?

• 10 times
• 4 times
• 2.5 times
