What does replacement mean in probability?
When the sample is drawn, it is placed back where it was taken from and if subsequent draws are made, it could be selected again.
What is the probability of drawing a king and a jack in two successive draws from a deck of cards with replacement?
It is 1/169 = 0.005917, approx.
Comparision between binomial plus normal plus hypergeometric distribution?
The binomial distribution is a discrete probability distribution which describes the number of successes in a sequence of draws from a finite population, with replacement. The hypergeometric distribution is similar except that it deals with draws without replacement. For sufficiently large populations the Normal distribution is a good approximation for both.
Kyle has three short straws four medium straws and six long straws If he randomly draws two straws one at a time without replacement what is the probability that both are short straws?
1/26
What is the probability of drawing a queen and a heart in two separate draws with card replacement?
2*(4/52)*(13/52) = 2*(1/13)*(1/4) = 1/26
What is the probability of drawing three aces in a row without replacement?
The probability of drawing aces on the first three draws is approx 0.0001810
You have 12 marbles 8 are blue 4 are green what is probability one of each color is chosen on the first two draws?
If the two marbles are drawn without replacement, the probability is 16/33.

What is the probability of drawing at least one spade in two draws without replacing?
It is approx 0.44
A bag of letter tiles contains 5 As 3 Bs and 2 Cs what is the probability of picking ABC in order in three draws from the bag without replacement?
The probability of picking ABC, in that order, from 5 A's, 3 B's, and 2 C's, without replacement, is (5 in 10) times (3 in 9) times (2 in 8), or 30 in 720, or 3 in 72, or 1 in 24.
What is the probability of drawing an ace then a diamond on two draws with replacement?
4/52 x 13/52 = 1/13 x 1/4 = 1/52
What is the probability of selcting two s's if the first card is not replaced before selcting the second card?
There are no s's in a standard deck of cards, so the probability of selecting any s's, in any sequence of draws, in any strategy of replacement is exactly zero.
What is the probability of drawing a queen and a heart in two separate draws with card replacement?
2*(4/52)*(13/52) = 2*(1/13)*(1/4) = 1/26
If a box contains three blue cards and three white cards If two cards are drawn one at a time find the probability that both cards are blue if the draws are made with replacement?
The probability of drawing two blue cards froma box with 3 blue cards and 3 white cards, with replacement, is 1 in 4, or 0.25.The probability of drawing one blue card is 0.5, so the probability of drawing two is 0.5 squared, or 0.25.
