What is the difference between probability with replacement and without replacement?

Back

With replacement means that after an item is selected, it is returned to the original set before the next selection. Without replacement means that once an item is selected, it is not returned to the set for the next selection.

If I draw a card from a deck and do not replace it, how does it affect the probability of the next draw?

Back

Not replacing the card changes the total number of cards in the deck, which affects the probability of drawing any subsequent card.

What is the probability of drawing two pennies from a box containing 10 pennies without replacement?

Back

The probability of drawing the first penny is 10/25. After drawing one penny, there are 9 left out of 24 total coins, so the probability of drawing a second penny is 9/24. The combined probability is (10/25) * (9/24) = 3/20.

How do you calculate the probability of drawing a red card and then a spade with replacement?

Back

The probability of drawing a red card is 26/52. Since the card is replaced, the probability of drawing a spade remains 13/52. The combined probability is (26/52) * (13/52) = 1/8.

What is the probability of drawing a green marble first and a yellow marble second with replacement?

Back

The probability of drawing a green marble is 2/11. Since the marble is replaced, the probability of drawing a yellow marble is 3/11. The combined probability is (2/11) * (3/11) = 6/121.
