Pseudo$-$randomness. Suppose that PRG : $\{0,1\}^$n $-->\{0,1\}^$p$($n$)$

be a pseudo$-$random generator that expands an

n$-$bit string to a

p$($n$)-$bit string, where p$($n$)>$ n

is a polynomial. You work for a Casino and can either buy a hardware random device $($blackbox$)$ that produces true random bits, or you can sample a seed and use the pseudo$-$random generator to generate pseudo$-$randomness.

What is the advantage of using a pseudo$-$random generator in this application?
