In some cultures, the number 4 is unlucky. You don’t want to take any chances, so you try not to do anything that involves number 4. One morning, as you are eating breakfast, you accidentally put 4 strawberries on your cereal. After you finish breakfast you realize your mistake, but since you are usually careful not to use number 4, you think you will be okay. On your way to work, you decide to drive slowly to make sure you won't be affected by the 4 strawberries. The driver behind you is texting and doesn't realize you are driving slowly, and he accidentally rear-ends your car. Does this prove that number 4 is unlucky? Explain.
