A new clothing store advertises that during its Grand Opening every customer that enters the store can throw a bouncy 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 none of the first three customers gets more than a 30% discount?
