Answer
$\frac{1}{195,249,054}$
Work Step by Step
Because the order is not important, we can use the combination rule to determine the number of possibilities: $\frac{59!}{(59-5)!5!}=5,006,386$.
By using the fundamental counting rule we can get the number of possibilities: $5,006,386\times39=195,249,054$. We also know that $probability=\frac{number \ of \ good \ outcomes}{number\ of\ all\ outcomes}$, therefore $P=\frac{1}{195,249,054}$.
