One takes the sample, then replaces the sample back into the population, then draws another sample.<br /> <br /> ===Example===<br /> What is the probability of drawing four red cards in a row, with replacement?<br /> <br /> Probability of drawing a red card: 26/52, or 1/2.<br /> <br /> Probability of drawing four red cards in a row with replacement? 1/2&lt;sup&gt;4&lt;/sup&gt;<br /> <br /> ==Sampling without replacement==<br /> '''Sampling without replacement''' is much the same, except the sample is not returned to the population.<br /> <br /> ===Example===<br /> What is the probability of drawing four red cards in a row, without replacement?<br /> <br /> Probability of drawing a red card: 26/52<br /> <br /> Probability of drawing four red cards? (26/52)*(25/51)*(24/50)*(23/49)<br /> <br /> As we removed a card, we didn't replace it, so the population size went down.<br /> <br /> [[Category:Probability and Statistics]]</div>
