Probability with replacement - Explanation & Examples

Webb"With replacement" means that once we select the first ball we put it back in the box before we select the second ball. Drawing with replacement makes the draws independent of each other, since the color of the first ball drawn does not affect the color of the second ball. If we randomly select two balls from the box: Webb28 dec. 2024 · When we sample without replacement, the items in the sample are dependent because the outcome of one random draw is affected by the previous draw.
