Answer:
e) 0.14
Step-by-step explanation:
We solve this problem building the Venn's diagram of these probabilities.
I am going to say that:
A is the probability that a driver does not have a valid driver's license.
B is the probability that a driver does not have insurance.
We have that:
In which a is the probability that a driver does not have a valid driver's license but has insurance and is the probability that a driver does not have any of these things.
By the same logic, we have that:
We start finding these values from the intersection.
4% have neither
This means that
6% of all drivers have no insurance
This means that . So
12% of all drivers do not have a valid driver’s license
This means that
So
The probability that a randomly selected driver either fails to have a valid license or fails to have insurance is about
So the correct answer is:
e) 0.14
