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