MM-INDEPENDENT AND DEPENDENT EVENTS

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 two times, is it independent or dependent probability?

• Independent

• Dependent

Dependent probability happens when the first item is not replaced, causing the total outcomes to decrease by 1.

• true

• false

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

• True

• False
