Let {tex}\bf{E} {/tex}be the event of hitting the boundary.

Then,

{tex}\sf P(E) = \dfrac{\sf Favourable \:outcomes}{\sf Total\:number\:of \:outcomes} = \dfrac{6}{30} = \bf{0.2}{/tex}

Now,

{tex}\underline{\bf{Probability\:of\:not\:hitting\:boundary}} :{/tex}

{tex}\sf 1-P(E) \\ \\ \implies 1-0.2 \implies \boxed{{\bf{0.8}}} {/tex}
