How many DIFFERENT 5-card hands can be dealt from a standard deck of 52 cards???
What Ranger SVO is saying is that order is not important. For example,
ACE,TWO,TRHEE Spades is considered the same as,
TWO,THREE,ACE Spades. Thus, this is a combination problem.
Thus, $\displaystyle \left( \begin{array}{c} 52\\5 \end{array} \right)=2598960$
