three to make 4 blue and 4 red balls. That means there's an equal chance or a 1 in 2 chance.

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.
A bag contains 4 red marbles and 5 blue marbles If two marbles are chosen at random what is the probability of getting two red marbles?
1/6Because:There is a 4 in 9 chance of picking a red ball the first time and 3 in 8 chance of picking a red ball the second time. The chance of picking two reds as the first two balls is 4/9 x 3/8 or 12/72 or 1/6
There are two identical bottles One bottle contains 2 green balls and 1 red ball The other contains 2 red balls A bottle is selected at random and a single ball is drawn What is the probabilit?

6 Is how many different combinations there are
What is the probability of pulling a black ball and then a green ball if there are 3 red balls 3 green balls 3 blue balls and 3 black balls?
3/12*3/11 = 9/132, or 6.818%.
What is the probability of picking a ball from a bag containing 4 red balls 3 green balls 2 yellow balls?
That depends. Picking a red ball is 4/9 Picking a green ball is 3/9 = 1/3 Picking a yellow ball is 2/9. Picking a ball is 9/9 or 1 because you'll always take one.
What is the probability of picking a red ball out of a bag containing 3 red balls 4 blue balls and 6 green balls?

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.

How can you find the height of a cylinder that contains 3 tennis balls with a radius of 3cm?
If the radius of each tennis ball is 3cm, then the diameter of each ball would be 6 centimeters. And since there are 3 balls, the height of the cylinder would be 18 centimeters.
How many illegitimate balls in an over in a cricket match?
By illegitimate, I presume you refer to a no-ball or a wide. Under current rules an over contains 6 balls. Some years back, 8-ball overs were used in Australia if nowhere else. For an over to be complete, 6-balls not including a wide or no-ball must be bowled. If an illegitimate ball is bowled, it must be rebowled. The most illegitimate balls bowled in one over was an over bowled by Curtly Ambrose in his final test on Australian soil which contained 9 no-balls - a total of 15 balls.
