• 2/25

• 3/5

• 2/3

Suppose a number cube is rolled twice. What is the probability that an odd number will show both times?

• 1/3

• 1/2

• 1/6

• 1/4

Bag A contains 9 red marbles and 3 green marbles. Bag B contains 9 black marbles and 6 orange marbles. Find the probability of selecting one green marble from bag A and one black marble from bag B.

• 3/20

• 1/4

• 3/31

• 2/27

Find P(red marble with replacement, then black marble).

• 2%

• 10%

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

• Independent

• Dependent

If you flip a coin then roll a number cube, is it independent or dependent probability?

• Independent

• Dependent

If you flip a coin two times, is it independent or dependent probability?

• Independent

• Dependent

Independent probability happens when the probability of the first event does not affect the probability of the second event.

• True

• False
