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 draw
gave 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 %
The probability of drawing an Ace, King, and Queen from a standard deck of 52 cards, with replacement, is (4 in 52)3 or 64 in 140608, or 1 in 2197, or about 0.0004552.
O.25
If you draw 40 cards without replacement the probability is 1! If you draw just one, the probability is 1/4.
The probability, if you draw 40 cards, without replacement, is 1. That is, it is a certainty. The probability on a single random draw is 1/4.
It is 1/169 = 0.005917, approx.
The probability of drawing aces on the first three draws is approx 0.0001810
The probability of drawing an Ace, King, and Queen from a standard deck of 52 cards, with replacement, is (4 in 52)3 or 64 in 140608, or 1 in 2197, or about 0.0004552.
The probability is 1 if you draw three balls without replacement. If only one draw, it is 3/5.
O.25
The probability of drawing a queen or king, in a single randomly drawn card, is 2/13. The probability of drawing one when you draw 45 cards without replacement is 1. The probability of choosing has nothing t do with the probability of drawing the card. I can choose a king but fail to find one!
The probability of drawing three black cards one at a time with replacement from a standard deck of 52 cards is 1/3x1/2x26/52, which is 0.833.
If you draw 40 cards without replacement the probability is 1! If you draw just one, the probability is 1/4.
The probability, if you draw 40 cards, without replacement, is 1. That is, it is a certainty. The probability on a single random draw is 1/4.
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.
The answer depends on how many cards are drawn. If 40 are drawn without replacement, from a normal deck, the probability is 1. If 3 are drawn the probability is 0!
It is 1/169 = 0.005917, approx.
The probability, if you draw 40 cards, without replacement, is 1. That is, it is a certainty. The probability on a single random draw is 1/4.
