According to the tree diagram below, what is the probability that someone buys a book that is paperback and fiction?
2 answers:
Let
x-----------> the probability that someone buys a book that is paperback
y----------> the probability that someone buys a book that is a fiction
P-----> the probability that someone buys a book that is paperback and fiction
we know that
so
substitute the values
therefore
<u>the answer is the option A</u>

Given:
The equation is:
To find:
The graph of the line that contains ordered pairs that are solutions of the given equation.
Solution:
We need to find the graph of the given equation.
We have,
At , we get
So, the x-intercept of the given equation is at point (0,4).
At , we get
So, the y-intercept of the given equation is at point (4,0).
From the given graphs it is clear that the line in option C has x-intercept at point (0,4) and y-intercept at point (4,0).
Therefore, the correct option is C.
