\
c.
Step-by-step explanation:
Let
are the events that denotes the good drive, medium drive and poor risk driver.

Let A be the event that denotes an accident.



The company sells Mr. Brophyan insurance policy and he has an accident.
a.We have to find the probability Mr.Brophy is a good driver
Bayes theorem,
We have to find 
Using the Bayes theorem

Substitute the values then we get


b.We have to find the probability Mr.Brophy is a medium driver

c.We have to find the probability Mr.Brophy is a poor driver

- Simplify both sides of the equation
=>x+5+4−5=x+54
=>x+5+4+−5=x+54
=>(x)+(5+4+−5)=x+54(Combine Like Terms)
=>x+4=x+54
=>x+4=x+54
- Subtract x from both sides
=>x+4−x=x+54−x
=>4=54
- Subtract 4 from both sides
=>4−4=54−4
=>0=50
3^2 goes onto the left side of the triangle
5^2 goes onto the bottom
x^ goes on the slant part of the triangle
