the library has 200 books in the fiction section 300 in the reference section 250 biographies and 250 nonfiction. if selected randomly what is the probability of selecting a nonfiction book as a percent .A. 250%B. 75%C. 25%D. 13%

Respuesta :

to determine the probability of getting a non-fiction book we need to find the coefficient between the number of non-fiction books and the total number of books. The total number of books is:

[tex]\begin{gathered} N_B=200+300+250+250 \\ N_B=1000 \end{gathered}[/tex]

Now we find the probability:

[tex]P=\frac{250}{1000}=0.25[/tex]

The probability as a percentage is 25%
