If you draw 5 balls with replacement from an urn containing white balls and black balls is the probability of getting 3 white balls always higher than if you draw the balls without replacement?
Marcusm1989
The probability of getting 3 white balls in a draw of 5 balls with replacement from an urn containing white balls and black balls is always greater than the same test without replacement, because the number of white balls decreases when you draw a white ball and do not replace it.
The ratio of white to black with replacement is constant, and is always less than one, assuming there is at least one black ball. The ratio of white to black without replacement decreases each turn, and is still less than one, and is less than the previous ratio, unless the question asked about 2 white balls or less.

What is the probability of getting a black 4 out of a 52 deck of cards?
If you pick enough cards, without replacement, the probability is 1. The probability for a single random draw is 1/26.
What is probability without replacement?
completely useless.
What is it called when you pick an object and do not return it in probability?
When you pick an object and do not return it, in probability it is termed "without replacement".
Why are the With Replacement and Without Replacement probabilities different?
Because with replacement, the total number of possible outcomes - the denominator of the probability ratio - remains the same. Without replacement the number of possible outcomes becomes smaller.
Margaret had a bag containing 5 red chips 5 blue chips and 5 yellow chips. What is the probability of drawing two red chips in two draws without replacement?
The probability of getting a red chip on the first draw is 5/15.The probability of getting a red chip on the second draw, given that the first drawgave a red chip that was not replaced in the bag is 4/14.The probability that the first and second draw give a red chip is ;5/15 x 4/14 = 2/21 ≈ 0.0952 = 9.52 %
What is the probability of getting a diamond and five without replacement?
The answer depends on how many cards are drawn.

What is the probability of getting two prime numbers 1-10?
The probability of getting two prime numbers when two numbers are selected at random and without replacement, from 1 to 10 is 2/15.
What is probability without replacement?
completely useless.
Five cards are drawn from an ordinary deck without replacement. find the probability of getting all red cards?
The probability is 7,893,600/311,875,200 = 0.0253

When you pick an object and do not return it, in probability it is termed "without replacement".
What is the probability of drawing two aces from a deck of 52 cards?
The answer depends on how many cards are drawn, and whether they are drawn with or without replacement. If 1 card is drawn, the probability is 0, if 50 cards are drawn (without replacement), the probability is 1. If only two cards are drawn, at random and without replacement, the probability is (4/52)*(3/51) = 12/2652 = 0.0045
If 5 cards are drawn from a deck of cards without replacement What is the Probability that at least One of the cards is a 3?
If five cards are drawn from a deck of cards without replacement, what is the probability that at least one of the cards is a heart?
What is the chance of drawing a red ball from a bag containing 3 red and 2 white balls?
The probability is 1 if you draw three balls without replacement. If only one draw, it is 3/5.
Three cards are chosen at random from a standard deck of cards without replacement What is the probability of getting 3 aces?
The probability of drawing the first ace is 4 in 52. The probability of getting the second ace is 3 in 51. The probability of getting the third ace is 2 in 50. The probability, then, of drawing three aces is (4 in 52) times (3 in 51) times (2 in 50), which is 24 in 132600, or 1 in 5525, or about 0.0001810
