Calculate average based on filter selected

Hi All, 

My original dataset has 14 rows and 2 column Company and Gender. 

Column_1 = CALCULATE(COUNTROWS(Sheet1),ALLEXCEPT(Sheet1,Sheet1[Company]))

Column_2 = CALCULATE(COUNTROWS(Sheet1),ALLEXCEPT(Sheet1,Sheet1[Gender],Sheet1[Company]))

Column_3 = DIVIDE(Sheet1[Column_2],Sheet1[Column_1])

I want to calculate Average Column, which is average of of Male and Female from column 3.

For Male it should be (.50+.29+.67)/3 =48.41 % 

How can i evaluate Average Column. Please guide. Thanks a Lot
