Question

The probability that a vehicle entering the Luray
Caverns has Canadian license plates is 0.12; the
probability that it is a camper is 0.28; and the probability
that it is a camper with Canadian license plates
is 0.09. What is the probability that
(a) a camper entering the Luray Caverns has Canadian
license plates?
(b) a vehicle with Canadian license plates entering the
Luray Caverns is a camper?
(c) a vehicle entering the Luray Caverns does not have
Canadian plates or is not a camper?

Answer 1

it says
The probability that a vehicle entering the Luray Caverns has Canadian license plates is 0.12
then asks
What is the probability that (a) a camper entering the Luray Caverns has Canadian license plates?

Answer 2

not much to this is there?

Answer 3

so 0.12 is correct for the answer ?

Answer 4

wel thanks for your help!

Answer 5

yes that is what it says right? not sure why you are told the answer and then asked the question
seems weird to me

Answer 6

the others might require some work though

Answer 7

do you know how to do them?

Answer 8

but part says the probability that its a camper and canadian license... so would the answer for part a be 0.09??

Answer 9

part A*

Answer 10

part and and B sounds the same to me but inverted... so confused

Answer 11

k lets go slow
and the first thing we should do is make a venn diagram, that will make all easier
then we can read the questions carefully and see what exactly they are asking

Answer 12

okay so how did you get the 0.03 and 0.09 and 0.17

Answer 13

shouldnt it be .19 instead of .17

Answer 14

maybe i made a mistake let me check

Answer 15

ok the probability of the intersection is \(.09\) that is, the probability of both
so i filled in the intersection first

Answer 16

yes so .28-.09 is .19 i think

Answer 17

then for the rest of A, since the total is \(0.12\) and we have already used up \(.09\) the remaining part is \(0.12-0.09=0.03\)

Answer 18

yeah you are right is screwed up
