this would be on a keno game and i would be playing nothing but the edge of the board. that is 32 numbers Keno draws 20 numbers the stats say that at least 7 to 9 of those 20 balls will land on the edge.if i play all 32 numbers 4 cards with 8 numbers on each what would be my odds of hitting a 7out of 8 or a 8out of 8?
