$\sf{\fbox{taking the maximum jersey as 100}}$

$\sf{doublets \: are \: 11,22,33,44,55,66,77,88,99}$

$\sf \purple{total \: duplets :9 }$

$\sf \green{total \: observations :100}$

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

$\sf \pink {\underbrace{ \overbrace{probability = \frac{9}{100} = 0.09 }}}$
