  • The probability NO two consecutive surprised test = $\begin{align*} &\frac{4}{5}*\frac{4}{5} = \frac{16}{25} \\ \end{align*}$
  • The probability that the student does not miss these two test = $\begin{align*} \frac{16}{25} \\ \end{align*}$
  • The probability that the student misses at least $1$ test = $\begin{align*} 1- \frac{16}{25}  = \frac{9}{25} \\ \end{align*}$
