Question

An insurance company looks at its auto insurance customers and finds that
a) All insure at least 1 car
b) 85% insure more than 1 car
c) 23% insure a sports car
d) 17% insure more than 1 car, including a sports car.
Find the probability that a customer selected at random insures exactly 1 car and it is not a sports car
Please, help me arrange it.

Answer 1

100%?
a) All insure at least one car

Answer 2

yup

Answer 3

Alright then. That wasn't so hard. :)

Answer 4

Wonder how it helps!!

Answer 5

..0.o?

Answer 6

it's not 100 though...

Answer 7

it's not 100, it's 100%

Answer 8

no it's not that either

Answer 9

why?

Answer 10

*Exactly 1 car* vs atleast 1 car

Answer 11

no, a says that every person in your sample group insures 1 car at the minimum

Oh... you have a point there Fionacci.

then 2 says of those 100%, 85% actually have at least 2 cars

Answer 14

So are you thinking 15% then?

Answer 15

no, not even there yet, you have to use proportions and it's not possible to be exact cause they overlap

Answer 16

because 23% of the 100% insure a sports car

Answer 17

but they can be in the 85% as well

Answer 18

at maximum it is 15%

Answer 19

Huh...beats me.

Answer 20

Answer 21

the important one is 4 though because that says 17% of the 100% but also intersects with the 85%

Answer 23

At the end up, I got nothing, hihihi ...

Answer 24

and fill in the blank, I have
