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

Answer:
1) Bigger sector = 168.8pi
1) Smaller sector = 56.3pi
2) Bigger sector = 529.9
3) Smaller sector = 176.6
Step-by-step explanation:
1) Bigger sector =
×pi×15×15
= 168.75pi
1) Smaller sector =
×pi×15×15
=
×pi×15×15
= 56.25pi
2) Bigger sector =
×3.14×15×15
= 529.875
2) Smaller sector =
×3.14×15×15
=
×3.14×15×15
= 176.625
