MIxing Concrete-propotion


I have a small back space which I want to pave. The area is about 10' by 6'.
I want to pour concrete about 4" thick over that area makin about 20 cu feet of concrete. About how much cement , sand and gravel do I need for that area.
What is the normal propotion of the 3 Ingredient to mix the concrete properly. Is it 3 sand 2 gravel and 1 cement? Just a guess.

About 3/4 yard of gravel, 1/2 yard of clean sand, 6 bags of 92lb portland cement.
Ratio: 1 cement, 2 sand, 3 gravel
Good luck!
