rubber cube onto a table that has squares labeled with discount amounts. The table is divided into ten regions. Five regions
award a 10% discount, two regions award a 20% discount, two regions award a 30% discount, and the remaining region
awards a 50% discount. Show your work. $$\begin{array} { | l | l | l | l | l | } \hline 10 & 30 & 10 & 30 & 10 \\\hline 20 & 10 & 50 & 10 & 20 \\\hline\end{array}$$
-What is the probability that the first customer to win a 30% discount is the sixth customer
that enters the store?
