6.Permutation and Combination
medium
Two packs of $52$ cards are shuffled together. The number of ways in which a man can be dealt $26$ cards so that he does not get two cards of the same suit and same denomination is
A
$^{52}{C_{26}}\;.\;{2^{26}}$
B
$^{104}{C_{26}}$
C
$2\;.{\;^{52}}{C_{26}}$
D
None of these
Solution
(a) $26$ cards can be chosen out of $52$ cards, in $^{52}{C_{26}}$ ways. There are two ways in which each card can be dealt, because a card can be either from the first pack or from the second. Hence the total number of ways ${ = ^{52}}{C_{26}}\;.\;{2^{26}}$.
