A&#9824; 2&#9824; 3&#9824; 4&#9824; 5&#9824; 6&#9824; 7&#9824; 8&#9824; 9&#9824; 10&#9824; J&#9824; Q&#9824; K&#9824;</font> 
A&#9827; 2&#9827; 3&#9827; 4&#9827; 5&#9827; 6&#9827; 7&#9827; 8&#9827; 9&#9827; 10&#9827; J&#9827; Q&#9827; K&#9827;

That's 22 out of 52, which we make into a fraction {{{22/52}}} which
reduces to {{{11/26}}}
