Answer:
The least amount of balls to take out from a bag containing red, green, and blue balls to ensure that you have taken out at least 2 green balls, assuming replacement after each draw, is 3.
Explanation:
To ensure that you have taken out at least 2 green balls from a bag containing red, green, and blue balls, assuming replacement after each draw, follow these steps:
First Draw:
Draw a ball from the bag.
This could be any colour (red, green, or blue).
Second Draw:
If the first ball drawn is not green, draw another ball.
This ensures that you have taken out at least 2 green balls, as the second green ball is guaranteed to be drawn by the second or third draw due to replacement after each draw.
Therefore, the least amount of balls to take out to ensure that you have taken out at least 2 green balls, assuming replacement after each draw, is 3.
