Question 2 • (OC27) MATH COLL LIB ARTS-1207350-S2-Maguire-D'Aquino

Which are dependent events? Check all that apply.choosing 2 socks from a drawer, without replacementflipping a coin 4 timespicking 4 cards from a deck, one after the otherrolling a number cube twice spinning a spinner and rolling a number cube

Answer
A
choosing 2 socks from a drawer, without replacement
B
flipping a coin 4 times
C
picking 4 cards from a deck, one after the other
D
rolling a number cube twice
E
spinning a spinner and rolling a number cube

Explanation

Events are dependent when the outcome of one event changes the probabilities of later events. Choosing socks without replacement changes which socks remain in the drawer, and picking cards one after another changes which cards remain in the deck. Coin flips, number-cube rolls, and a spinner spin paired with a number-cube roll do not change the probabilities of later outcomes.
