Question

The table shows the types of movies and the numbers of DVDS rented by customers at a store in one day. Based on the data in the table, what is the probability that random customer will rent a drama?

Answer 1

Let:

A = Rental a Drama Movie

a = Number of rentals of drama movies

N = Total number of rentals

the probability that random customer will rent a drama is:

$\begin{gathered} P(A)=\frac{a}{N} \\ where\colon \\ a=25 \\ N=25+35+50+15=125 \\ so\colon \\ P(A)=\frac{25}{125} \\ P(A)=\frac{1}{5}=0.2 \end{gathered}$
