A bag consists of 10 balls each marked with one of the digits 0 to 9. If four balls are drawn successively with replacement from the bag, what is the probability that none is marked with the digit 0?

Question

$\begin{array}{1 1} (\large \frac{9}{10})^4 \\ (\large \frac{3}{10})^4 \\ (\large \frac{1}{10})^4 \\ (\large \frac{7}{10})^4 \end{array}$
