Final answer:
The probability of not being involved in a car accident is approximately 0.9996 or 99.96%.
Step-by-step explanation:
To find the probability of not being involved in a car accident, we need to subtract the probability of being involved in a car accident from 1. The probability of being involved in a car accident is 1 in 2500, so the probability of not being involved in a car accident is:
1 - 1/2500 = 2499/2500 = 0.9996
Therefore, the probability of not being involved in a car accident is approximately 0.9996 or 99.96%.
