The graph shows the number of each kind of book in hero's personal library. a book is chosen randomly. what is the probability that the book chosen is a biography? a)2/15 b)4/15 c)1/30 d)1/4

From the graph, it is found that there is a probability that the book chosen is a biography, and the correct option is given by option A.

In this problem:

Thus:

probability that the book chosen is a biography, and the correct option is given by option A.

A similar problem is given at link

A is the right answer .Probability of the book chosen is a biography is .

Step-by-step explanation:

According to the given graph or pie chart

The number of biography books=4

Total books= Romance books+ Science fiction books+ Biography books+Adventure books =2+14+4+10=30

Let B be the event of choosing a biography book then

Probability of the book chosen is a biography P(B)=

Therefore, Probability of the book chosen is a biography is  .

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
