Probability of Independent Events — Quiz

Question 7 • Integrated Math II CR SUSD (EX)

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

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

Explanation

The rolls are independent because the result of one roll does not affect the result of any later roll, even though all four happened to be 2. The experiment is compound because it includes four rolls, so multiple events occurred. Therefore, the best description is “Independent” and “Compound.”
