Sampling with replacement is used to find probability with replacement. Because it is easier to work out the probabilities of 0 and 3 red cards we will calculate those probabilities first. It can be calculated by dividing the number of possible occurrence by the total number of options. The new probabilities are as follows: P (C) = 12/51 (because there are only 12 clubs left in the deck) P (D) = 13/51 (there are still all 13 diamonds left, but there are only 51 cards remaining to choose from) Thus, by drawing a club from the deck, we changed the probabilities P (C) and P (D). These can be handy if you are playing card games or just trying to understand probability.
