@ GMAT GURU NY - Can you please explain the statement
Total possible ways:
Any arrangement of WWMM will yield exactly 2 W and 2 M.
Thus, the result above must be multiplied by the number of ways to arrange the 4 elements WWMM.
Number ways to arrange WWMM = 4!/(2!2!) = 6.

@gmatguruny -- is it ok to use simple numbers, #1 for the value of X?
I thought one should steer clear of using the number 1 when plugging solving such questions like this.
