Let’s engage in a fun logic/math/stats word problem, shall we?

Today I went to my first dissertation defense for someone in my cohort. The 2007 Curriculum & Instruction cohort consisted of 12 people – 7 women and 5 men. By the end of the second year, one woman and one man had dropped out, so that leaves 6 women and 4 men remaining. Now, the end of our fifth year, 4 have successfully defended.

Out of those 4, how many are women and how many are men? What ought the breakdown be, if everything else is equal?

I shall reveal the answer after I get some thoughtful responses!
