Identifying Independent and Dependent Events Practice

A marble bag contains 3 red marbles, 4 gray marbles, 6 white marbles, and 5 black marbles. What is the probability of randomly drawing a red marble and then a gray marble if the first marble is replaced?

• 1/9

• 1/27

• 1/6

• 2/9

Two marbles are drawn from a container in such a way that the first marble drawn is replaced before selecting the second marble. Does the outcome of the first draw affect the outcome of the second?

• Yes

• No

The outcome of one event does not affect the outcome of the other event.

• independent event

• dependent event

The outcome of one event does affect the outcome of the other event.

• independent event

• dependent event

Clara picks a marble at random, puts it back, and then picks another marble at random.

• independent

• dependent

A bag contains some red-colored and some blue-colored marbles. First a red-colored marble is drawn and then, without replacing the first marble, a blue-colored marble is drawn. Are the two events independent or dependent?

• Independent

• Dependent

A coin is tossed and then the spinner is spun. Determine the probability that you toss Heads and spin a Red.

• 1/6

• 1/10

• 0

• 1/12

If you draw out a red marble, keep it, then draw out a blue marble, is it independent or dependent probability?
