A bag contains 3 red balls and 4 green balls randomly draw one ball then replace it and randomly draw a second what is the percentage?
Drawing one red ball out of a bag that contains 3 red balls and 4 green balls is 3 in 7. If we are to randomly select one ball out of the bag and replace it (I assume with the same ball) then there are still 3 red balls and 4 green balls. The odds are still 3 in 7. It doesn't matter how many times you draw. Every time you draw a ball you have a 3 in 7 chance of pulling out a red ball.

Why does concentration increase the reaction more?
Imagine the molecules are like soccer balls and the container is like a room. If you're kicking 1 ball around the room at only 1 other ball, the chances of you randomly hitting one ball with the other are slim (low concentration). If you're kicking 200 balls at the same time at another 200 balls in the same room, your chances of 1 ball hitting another are massively increased (high concentration). More balls, more reactions.

What order do you pot ball in pool?
That depends on which pool game you're playing. In 8-ball, you choose either the solid balls or the stripe balls and must pot those before attempting the 8-ball for the win. In 9-ball, you must pocket the balls in numerical order starting with the lowest numbered ball--potting the 9-ball on a legal shot wins the game. In 14.1, you shoot at anything. In one-pocket, when playing without handicaps, you shoot for any ball and the first player to make 8 balls in his/her designated pocket wins.
