What else can I help you with?
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

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.

What is inside a inflated ball?
