Steve's barking; America the math challenged country

A lot has been said that the top tech companies aren't hiring minority ( not counting Asians).

Now after a little research on my part I have discovered that the top tech companies only hire 20% of the computer science graduates. 

My research indicates that only 12% of computer science grads are women.

My research indicates that 10 % of computer science grads are minorities.

That being said what percentage of new hires should be women and what percentage should be minority?

Hint women should not make up 12% and minorities should not make up less then 10%.

* My research isn't that good because I did on Google and Google has been falling down on the job.

I ask simple question and I'm steered to sites that are at best remotely related to what I ask.

Now if my math isn't off I would say that female hires should be 2.4 % of hires and minorities should be 2%.

Now if I would rate my math ability on 1 to 10, I would rate it a 2.
