Answer: Probability that at least one of them has a car crash during a year is 0.177.
Step-by-step explanation:
Since we have given that
Probability of car crashing during a year in a certain country = 0.0478
Probability of not getting any car crash during a year = 1-0.0478 = 0.9522
We need to find the "Probability that at least one of them has a car crash during a year ":
Probability that at least one of them has a car crash during a year=1-P(not getting any car crash )
[tex]1-(0.9522)^4\\\\=1-0.822\\\\=0.177[/tex]
Hence, Probability that at least one of them has a car crash during a year is 0.177.
