Probability of Independent Events

Question 7 • *CR CCSS Math 2 S2 [M2960OX]

Juan rolls a 6-sided number cube 4 times. Each time, the result is 2. Which best describes the events?

Answer
D
Dependent: Each outcome was the same. Simple: One single number cube was rolled.
I
Independent: Each outcome is unaffected by previous outcomes. Simple: One single number cube was rolled.
D
Dependent. Each outcome was the same. Compound: Multiple events occurred.
I
Independent: Each outcome was unaffected by previous outcomes. Compound: Multiple events occurred.

Explanation

Each roll is independent because the result of one roll does not affect the result of the next, even though all four rolls happened to land on 2. The situation is compound because it includes four rolls, or multiple events. Therefore, “Independent” and “Compound: Multiple events occurred” is correct.
