Hey Everyone
Not really sure how I would evaluate these:
10P4
_
P(A) when P(A) = 10/11
and
10C2
Thought i'd shoot them out there and see if anyone could guide me in the right direction.
This posting is almost impossible to read (decode).
Here is my take on it.
$\displaystyle _{10} P_4 = \left( {10} \right)\left( 9 \right)\left( 8 \right)\left( 7 \right) = \frac{{10!}}{{\left( {10 - 4} \right)!}}$.
While $\displaystyle _{10} C_2 = \frac{{10!}}{{2!\left( {10 - 2} \right)!}} = \frac{{10 \cdot 9}}{{2 \cdot 1}}$
I must say that I doubt this is your problem.
