$\sf\footnotesize\fbox {\underline{Considering \: the \: maximum \: jersey \: no. \: is \: 100}}$

$\sf{then, the \: perfect \: squares \: from \: 1 - 100 \: are : }$

$\sf \purple{1,4,9,16,25,36,49,64,81,100}$

$\sf \blue{probability = \frac{favourable \: outcomes}{total \: outcomes} } \\$

$\sf \pink{ \underbrace{ \overbrace{probability = \frac{10}{100} = 0.1 } }}\\$

$\sf \fbox{ \footnotesize {\underline{Considering \: the \: maximum \: jersey \: no. \: is \: 1000}}}$

$\sf{then, the \: perfect \: squares \: from \: 1 - 1000 \: are : }$

$\sf \blue{probability = \frac{favourable \: outcomes}{total \: outcomes} } \\$

$\sf \pink{ \underbrace{ \overbrace{probability = \frac{31}{100} = 0.31 } }}\\$
