Question 6 • Pre-Algebra B

Which describes dependent events?

Answer
A
drawing a blue marble and then a yellow marble without replacement from a bag of marbles.
B
drawing the ace of spades from a deck of cards, putting it back into the deck, and drawing the king of spades.
C
rolling a six-sided number cube and getting an even number, then rolling the same six-sided number cube and getting an even number again
D
flipping two coins at the same time and getting heads on one and tails on the other

Explanation

Dependent events are events where the outcome of the first event changes the probability of the second. In A, the first marble is not replaced, so drawing a blue marble changes how many marbles remain and can change the chance of drawing a yellow one. The other choices involve replacing the card or using separate rolls or coin flips, so their outcomes do not affect one another.
