The difference between 8 and n looks like,
8 - n
Answer:
The probability that a car that comes into the garage needs both an oil change and a tire rotation is
.
Step-by-step explanation:
The conditional probability of an event <em>B</em> given that another event <em>A</em> has already occurred is:

Denote the events as follows:
<em>X</em> = cars brought in for service need an oil change
<em>Y</em> = cars brought in for service need a tire rotation
The information provided is:


Compute the value of P (X ∩ Y) as follows:




Thus, the probability that a car that comes into the garage needs both an oil change and a tire rotation is
.
b×h=a
this is how to represent it and it is a direct variation.
Step-by-step explanation:
2a -5a +8a.
2a +8a -5a
10a -5a = 5a
14-7=7
<em>Answer=5a+7</em>
