The number of ways of dividing $52$ cards amongst four players so that three players have $17$ cards each and the fourth player just one card, is
A
$\frac{{52\;!}}{{{{(17\;!)}^3}}}$
B
$52\;!$
C
$\frac{{52\;!}}{{17\;!}}$
D
None of these
(IIT-1979)
Solution
(a) For the first set number of ways $^{52}{C_{17}}$.
Now out of $35$ cards left $17$ cards can be put for second in $^{35}{C_{17}}$ ways similarly for $3$ rd in $^{18}{C_{17}}$.
One card for the last set can be put in only one way.
Therefore the required number of ways for the proper distribution
$ = \frac{{52\,!}}{{35\,!\,17\,!}} \times \frac{{35\,!}}{{18\,!\,17\,!}} \times \frac{{18\,!}}{{17\,!\,1\,!}} \times 1\,! = \frac{{52\,!}}{{{{(17\,!)}^3}}}$.
