Question 1101329
<pre>
Choose the 2 ranks for the pair in 13C2 ways.
Choose the 2 suits for the lower ranked pair in 4C2 ways.
Choose the 2 suits for the lower ranked pair in 4C2 ways.

So the numerator of the probability is (13C2)(4C2)(4C2)

The denominator is (52C4)

So the probability is {{{((13C2)(4C2)(4C2))/(52C4)}}}

or {{{216/20825}}} or as an approximate decimal {{{0.01037214886}}}
