A manager has been given the table shown below and is asked to generate random numbers.Which of the following statements is TRUE?
$\begin{array}{|c|c|}
\hline\text { Range } & \text { \# Customers } \
\hline 00-49 & 0 \
\hline 50-79 & 1 \

\hline
\end{array}$
A) There are no customers in the store 49 percent of the time.
B) The probability of having one customer in the store is 0.30.
C) The relative frequency of having two customers in the store is 0.80.
D) If we randomly choose the numbers 0 through 99 enough times, about 99 percent of the time we will have two customers in the store.

The table shows that the probability of having 0 customers in the store is 0, the probability  of having 1 customer in the store is 1/100 or 0.01, and the probability of having 2 customers in the store is 0.98. Thus, statement A is false, statement B is true, statement C is false (the relative frequency of having two customers would be 0.98 or 98%), and statement D is false as it is not possible to guarantee having two customers 99% of the time just by generating random numbers within the given range.
