According to the tree diagram below, what is the probability that someone buys a book that is paperback and fiction?

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
[tex]x=0.65[/tex]
[tex]y=0.45[/tex]
[tex]P=x*y[/tex]
so
substitute the values
[tex]P=0.65*0.45=0.2925[/tex]
therefore
the answer is the option A
[tex]0.2925[/tex]
