Question

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

Answer 1

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

$x=0.65$

$y=0.45$

$P=x*y$

so

substitute the values

$P=0.65*0.45=0.2925$

therefore

the answer is the option A

$0.2925$
