Independent and Dependent Probability Review

If a number cube is rolled twice, what is the probability that an odd number will show both times?

• 1/4

• 1/2

• 1/8

• 3/4

True or False: Dependent probability happens when the first item is replaced, causing the total outcomes to increase by 1.

• True

• False

• Dependent probability does not involve replacement

• Dependent probability increases total outcomes

What is dependent probability?

• Dependent probability occurs when the outcome of one event affects the outcome of another event.

• Dependent probability is the likelihood of an event occurring without any influence from other events.

• Dependent probability refers to the probability of an event occurring in isolation from other events.

• Dependent probability is the probability that remains constant regardless of other events.

What is independent probability?

• Independent probability occurs when the outcome of one event does not affect the outcome of another event.

• Independent probability is when two events are guaranteed to happen together.

• Independent probability refers to the likelihood of an event occurring based on previous outcomes.

• Independent probability is the probability of an event occurring in isolation from any other events.
