as total number of outcome = 99-9= 90 and favourable outcome = 17 I.e. 1 .hence 1/90 is the answer

$\mathsf{Total \ Outcomes \ = \ 90}$

$\mathsf{Favourable \ Outcomes \ of \ getting \ number}$
$\mathsf{17 \ = \ 1}$

${\boxed{\mathsf{\red{P(x) \ = \ {\dfrac{Favourable \ Outcomes}{Total \ Outcomes}}}}}}$

$\mathsf{P(getting \ number \ 17) \ = \ {\dfrac{1}{90}}}$

$\mathsf\blue{P(getting \ number \ 17) \ = \ {\dfrac{1}{90}} \ or \ 0.01}$
