<p>For the office vs cubicle problem, we list all possible arrangements using M for any man and W for any woman.</p>
<p>Office: M M M Cubicle: W W
Office: M M W Cubicle: M W
Office: M M W Cubicle: W M
Office: M W M Cubicle: M W
Office: M W M Cubicle: W M
Office: W M M Cubicle: M W
Office: W M M Cubicle: W M
Office: W W M Cubicle: M M
Office: W M W Cubicle: M M
Office: M W W Cubicle: M M</p>
<p>So there would be ten different arrangements, six of which have 2 M and 1 W in the office.
So the probability of 2 M and 1 W in the office is 6/10 or 3/5.</p>
