5 + 4 does not equal 11.

oh ya,sorry its my mistake, it should have been 6 in A and 5 in B which makes total A+B =11

The first thing you need to so is work out exactly how you want to divide them: 5 and 4 do not make 11 except in octal and I doubt that is what you want.
Assuming you want to divide an odd number into two "equal sized" crews, I'd do this:

Crew 1 = AvailableCrew / 2
Crew 2 = AvailableCrew - (AvailableCrew / 2)

This puts the larger crew of an odd value in Crew 2, but that can be swapped if you need. It equally sizes even counts.
