A manager has observed sales for a number of days and developed the following table of probabilities. Which of the following distributions would be most appropriate for modeling the daily sales?
$\begin{array}{|c|c|}
\hline \text { Daily Sales } & \text { Probability } \
\hline 100 & 0.40 \
\hline 200 & 0.05 \
\hline 300 & 0.50 \
\hline 400 & 0.05 \
\hline
\end{array}$
A) Normal distribution
B) Triangular distribution
C) Lognormal distribution
D) Integer uniform distribution
E) Custom discrete distribution

The table lists specific sales values with associated probabilities, which does not fit continuous distributions like normal, triangular, or lognormal, nor does it fit a uniform distribution which implies equal probability for all outcomes. This scenario is best modeled by a custom discrete distribution, where each sales figure has its own distinct probability.
