Step-by-step explanation:
Answer:
A. 7%
Step-by-step explanation:
We build the Venn's diagram of these probabilities.
I am going to say that:
A is the probability that a resident owns a car.
B is the probability that a resident owns a truck.
We have that:
In which a is the probability that a resident has a car but not a truck and is the probability that a resident has both a car and a truck.
By the same logic, we have that:
4% of residents own both a car and a truck.
This means that
56% of residents own a car
This means that . So
What is the conditional probability that a person who owns a car also owns a truck?
So the correct answer is:
A. 7%
Answer:
w=18
Step-by-step explanation:
Subtract 3x from both sides
-7-9x=8
add 7 to both sides
-9x=15
divide bothsides by -9
x=15/-9
Simplify
x=-5/3
