Answer:
There is a 4% probability that a customer buys three tires.
Step-by-step explanation:
We have those following percentages
60% buy four tires. This is also the probability that someone buys four tires.
22% buy two tires
14% buy fewer than two tires(one or none).
P% buy three tires
The sum of the percentages must be 100%.
So



There is a 4% probability that a customer buys three tires.
The midpoint of these two points is (-1, 8).
In order to find the midpoint, you must take the average of each part of the coordinates. You do this by adding them together and dividing by 2. We'll start with the x-coordinates.
(-1 + -1)/2 = -1
Now we'll use the y-coordinates.
(10 + 6)/2 = 8
This gives us the ordered pair of (-1, 8)
