<PRE><B>Question 1075990</B>
(a)
3 numbers followed by 3 letters:
{{{ 10*10*10*26*26*26 }}}
-------------------------------
(b)
What are all possible combinations of
POSITIONS of the 3 numbers and letters?
for instance:
NLNLNL
NLNLLN
NLLLNN
etc
That would be C( 6,3 )
{{{ 6! / ( 3!*( 6-3)!) }}}
{{{ 6! / ( 3!*3! ) }}}
{{{ ( 6*5*4*3*2*1 ) / ( 3*2*1*3*2*1 ) }}}
{{{ ( 6*5*4 ) / ( 3*2*1 ) }}}
{{{ 5*4 = 20 }}}
The answer is then
{{{ ( 10*10*10*26*26*26 )*20 }}}
definitely get a 2nd opinion on this.
